Slotting for resistances depends what other powers you have on when it's up. It has a base 70% damage resistance buff. As damage resistance cannot go above 90% there isn't any reason for getting more than that. Even Damage resistance debuffs are not affected by resistance above 90%.
If you have the energy passives ( Resist Elements, Resist Energies ) and keep temp invulnerability and unyielding on it's not worth slotting for resistance as a Inv tank has about 26% resistance to all without it. This means it puts your resistance to 96%, your S/L resist will be even higher than this.
If you have the passives or you keep unyielding on, 1 slot of resistance ( which gives 84% ) will cap you.
If you use Unstoppable by itself and don't have the passives you'd want 2 damage resistances.
The reason for turning off Unyielding is that when you crash you can turn it on quick.
Pros:
Lots of endurance available.
Immune to toggle drops
Capped resistances
Cons:
Only available 36% of the time ( 44% on average with Hasten ).
The crash can be messy.
Fights limited to 3 minutes.
I found the crash to be really nasty and enough to not bother with the powers unless fighting malta ( when it is really fun going on an Unstoppable Rampage squishing sappers ). However if you are willing to spend a while in debt learning to use it ( I didn't ) then it may well be useful for you.
I wouldn't use it against an AV, ever! But then against them you have the option of using defence inspirations, which can easily keep you going for the duration of an AV fight.
If you mean dropping all of the other shields to just use unstoppable you will have downtimes of something like 3-4 minutes every 3 minutes. Your teammates won't like you for that.

I've loved Unstoppable ever since I first took on the power with my Inv/SS tank.
Its a power that does give you a brief feeling of being the very hero that you are...you quite literally have people falling at your feet when you have this on!
General Information
===================
It is a situational power and used mainly when the chips are down and you're looking at a team wipe out.
I've used other tier 9 powers (Gabriel Knight...MoG, Eternal Light...Elude), however it is probably the most God-Mode power out of the lot of them that I've experienced.
Bonuses:
- 52.5% resistance to all types except psionic.
- Provides status-effect protection (hold, sleep, disorient, knock, immobolize (mag -6 through -12)).
- Provides boost to endurance regeneration.
Side Affects:
- Lasts for approximately 3 minutes.
- When it ends, it leaves you with no endurance and leaves you with 10% of your health.
The crash is the major downside...the only way I counteract is to pop a CaB and then hit Dull Pain (Earth Slotting...3Rechg / 1Heal).
I have Earth's Unstoppable slotted as 3Rechg / 3 DmgRes as I do tend to use it often. However it should just suffice with just 3DmgRes if you're only going to be using it rarely.
I usually remove my DmgRes shields (ie: Temp Invul / Unyielding...in particular, as this is your defence against status affects / Tough) so that I don't have to wait for them to recharge once the crash comes about...[edit entry...to justify why I have 3DmgRes in Unstoppable]

Unstoppable is a power that looks great and makes you feel like you could aggro the world and come out smelling like a rose bush just before i8 i respec'd it out of my tanker 'worst mistake ever!' i missed it really bad and was back in there once i obtained a freespec from the new issue as a long time user you will be able to determine when and where it is need and the more recent 'blinky' system allows you time you rest or cheese it from combat when it's gonna crash...
my recommended slotting 3 Recharge 1 resistance

Unthing has said much that i agree with. Ill add never underestimate end mods in the power in the face of a sapper.
Unstoppable crashes doesn't have to equal defeat. I have basically gone Unstoppable-->Dull pain period-->Unstoppable-->Dull pain period-->Unstoppable-->Dull pain period-->Unstoppable etc with hastened unstoppable.
Basically for one you can leave an AV taunted (heavy taunt slotting so he cant hit no one) then crash out of sight, toggle up, get back to AV and back to business or with a very good defender have buffs when needed and timed heals when needed. Velinia i think it was, has helped me go through chains of Unstoppable in front of Ghost Widow without a defeat and has no understanding of how unlikely most people will ever get to see that. An empath from a range of +70ft (and so unhittable of GWs aoes that are on me) had kept fort on (minimise chance of soul storm) and applied adrenalin boosts before crashes. An entire team of people could of attacked GW from behind, mostly at 80ft range and dropped her so that there was no defeats at all.
One time i got lucky with not getting hit whilst retoggling but sometimes due to endrec or fast blue you dont even detoggle and if ya can save lucks for the crash you reduce chances of getting hit and if you pop a break free prior you reduce the chance of finding out your being held. Conserve energy prior to crash helps you get toggled and fight from low end after.
Great thing about Unstoppable is its non externally detoggleable and so until it crashes, you can happily be soul stormed and get up after. A stonetank would kiss goodbye rooted, loose granite and be planted fast. I have seen stonetanks spend say 2 mins on her and get the "i am immortal best tank ever" attitude (actually been said) and then get their butts handed to them from soul storm, it'll get people eventually. We all play to maths, and we all can get lucky or unlucky regardless of skill on this one.
Against Psi AVs a insp tray made up of enough lucks and greens is a good idea plus tanking extra safely on route to AV so that you don't have to use them. Getting past say Children of Anger could simply be herd fast defeat fast or more of a controllers game etc. My controller putty-tats them and its stupid not to allow that

Hey nice to see a post from you I agree with
Unstoppable is imo the only remaining true godmode power post-ED in the game. I like it very much. It has all the good stuff and none of the drawbacks of granite during its uptime. Unstoppable+dull pain, within those three minutes the tank is, in a cartoony way, unstoppable. The crash however, is just as horrible as the uptime is good.. Balances out i guess. But crash does not equal death.
However, the unstop recharge is too slow for me to use it constantly. I do use it a lot however.
Free Radical:
heres my hints
- When you hit unstoppable, activate dull pain at the same time. Not only will this make you really hard to kill, but dull pain with 3 recharge slots recharges faster than unstoppable crashes, so this way you can both time the crash a little bit and ensure that dull pain is up when the crash comes. Dull pain is a power that goes well with unstoppable.
- Always carry catch of breaths in the tray. The bigger the better. Crash -> catch of breath -> dull pain -> retoggle. Few seconds vulnerability.
ps. tanking AVs unthing? I have tanked all three of recluses victory AVs at the same time using unstoppable and pulled Scirocco across entire zone once to drone him..
pps. The slotting? oh yeah uh, 3 recharge, 1 res, 2 endmod.
If you didn't notice from my post I'm not an Unstoppable fan. But I do know that I haven't used it enough to realise it's potential.
@Unthing ... Mostly on Union.
i'd just go for 3 recharge to be honest, its a really good power anyway, while running it i've not felt the need for that additional res slot that some people recommend.
as to using it all the time, you could try i used it a fair bit on my invul tanks and its always great fun, i'd recommend either running hero stats or getting a really easy to see digital clock to sit on your desk so you can time the crashing right.
i found vs even cons and +1 it was hardly ever used because when you'd need this vs even/+1s you're over the agro cap anywya so it wont be so much use. however anything higher than +3 you use it more.
i found once you get the crash routine timed well unstoppable can be crashing and back to fully toggled up and full end in about 10 seconds.
my crash routine was just before crash go into rest and detoggle all toggles, then as soon as its crashed you can retoggle up - in rest (as the cooldowns over) and 10 seconds of rest later full endurance.
if you're feeling lucky when in rest you can sometimes get away with not detoggling as the rest tick is high enough to stop the end crash detoggling you.

Thats your choice, you have great protection with just unstoppable but you have more if you have UY also running..
It's a pity Inv toggles don't recharge as quickly as Ice Armour toggles do - we wouldn't need to worry about detoggling before the crash then.

Actually I havent worried about detoggling myself at all.. Dull pain is the crucial part imo.
Guess its time experimenting with unstoppable.. at least if it goes wrong I might be well on the way to debt badges

I'd only detoggle Unyielding and then only if I've a little breathing space to actually think Usually it's a case of popping a few lucks when the icon starts blinking and then a catch a breath followed by Dull Pain. I generally don't see a need for running Dull Pain while Unstoppable as I have Aid Self to keep my health topped up.

Unstoppable+lucks+taunting from pillbox shield (it buffs but you have to get in shield before AVs tear pillbox down). Its possible to tank Scirroco, GW and Mako at once until all 3 get taken out. Problems in game ofc is other tanks/other players, you get the 3 AVs to have the backs to the other heroes and another tank will come along and make the AVs face the heroes putting heroes at greater risk or a key player to everyone elses survivability would stand next to you "needlessly" and get himself whacked and with you chaining taunt you cant tell people at the time how to play. If all 3 are close enough then when Mako placates you can taunt Ghost Widow and the taunt is an AoE and the taunt effect still showed up on Mako.
One time the fight duration against one AV was getting abit out of hand, my survivability worsening, i saw how much damage we had done realised i had to go unstoppable, clicked rage, went to town, dropped the AV and the moment the AV went down the crash happened. My mate went "timed that well" and i actually had.

That depends what you are tanking as aid self is interrupted by everything and their mother-in-law. Personally I like my 3212 hit points to go with the capped resistances... if for nothing else then for the godhood value. 
ps. also did you notice that you can use dull pain as a timer as well. When its back up, you have about 30 seconds to the crash and can make preparations.

@Unthing ... Mostly on Union.
Hey everyone,
Im the current trend (well at least format for me) what would be the best slotting for Unstoppable?
My use would be for an "oh no.. the <insert appropriate word> has hit the fan!". So in my case I would use it rarely and only when im in too deep.
I currently have 1 dmgresist and will be looking to add 3 recharge redux at a later date.
Also, whats the pros & cons for using unstoppable all the time instead of normal shields?
