Time to finish fixing Invulnerability

It is nitpicky. I agree, but its necessary. As was stated earlier, RPD gives S/L resist which is already covered by TI in that early stage. TH gives 5% def to all except psi. Now, lets not forget one important factor according to our devs, 1 def = 2 resist. So 5% def is like a 10% resist spike to everything.

I remember Castle mentioning a while back about adding +HP to Invulnerability. What ever happened about that?

You still have to prove that there is some reason to merit changing things up, which is time and effort on the part of the devs. If Invuln is on par with other sets, especially for the first 20 or so levels you are discussing for these changes, then such a change would not be warranted. In the case of changing Temp. Invulnerability's name, it probably would make sense, and not be that much work, or so I would guess, so you might get something there if you bring it up in a PM.

As it is, Invulnerability is plenty solid for its whole career, and is hardly weaker than other sets prior to level 20. RPD can be nice for times you are low on endurance and don't want to run TI, and of course the two stack quite nicely (unslotted, you're only 7% lower resists to Smash/Lethal than Fiery Aura gets slotted from its primaries). This is even nicer when you think about how much of the damage in those first 20 or so levels is mostly smash/lethal. Sure, a bit more defense would be nice, but all tanker sets don't have all their "tricks" yet at that point. WP can't get defense until 18, either, Fiery Aura doesn't have all its offense (same for Shields, not to mention all its defenses), Ice doesn't get Energy Absorption until 26, etc.

Again, Invulnerability overall might need some regen somewhere, as Castle once suggested himself (not sure what happened to that, if he's still planning on it, or looked at it and decided not to), but other than that, it's pretty solid. My Invuln Tanker is a little behind my WP Tanker in levels (35 as opposed to 49), but I haven't found Invlun to play particuarly weaker, and I'm running most of the same content with him. They just play different, Tanking well overall.

Remember, to get a change, the burden of proof falls on you to proove such a change is warranted. That's how it is.

I see absolutely no good reason to swap Tough Hide and RPD; in the low levels a mere 5% defense buff is, for all practical purposes, meaningless. It doesn't become really useful until you have defense from other sources to stack with it, which means after Invincibility.

I'd have to say I can't support moving a power that actually is useful at lower levels (RPD), albeit generally more so around 22, with one that really doesn't make any real difference until after Invincibility anyway (TH)... which, by some odd reason, is exactly where it comes available.

Swapping Temp. Invuln with RPD however is a slam dunk for AT's that get it as a secondary. If you were actually going to swap anything else, then swap Invincibility and Resist Elements; THAT would be a useful change. Not necessary by any stretch, but it would be a useful change.

Going from 0% to 5% of defense is nearly meaningless... but going from 25% to 30% is quite significant, and going from 40% to 45% actually DOUBLES the amount of protection. Defense works best when the values get higher. You'll never notice 5% of defense, but you most assuredly will notice the difference 40% to 45% makes.

Bottom line, there's no valid reason to swap RPD and TH and there are very valid reasons to leave them as-is. This would be a poor change and a nerf to low level Invuln.

Is it really that much to ask you to prove your own points?

SETUP
Assume a continuous stream of damage. Then assume the initial chance to hit is 50% (should be true at low levels in most cases). I am only looking at low levels so no enhancements, just the raw powers and you get:

RPD + TI + UY = 45% S/L resist, 10% F/C/E/N resist, 25% Def Debuff Def
so all S/L damage is reduced by 45%, all F/C/E/N damage is reduced by 10%

and TH + TI + UY = 35% S/F resist, 10% F/C/E/N resist, 5% S/L/F/C/E/N defense, 25% Def Debuff Def
so all S/L damage is reduced by 41.5%, all F/C/E/N damage is reduced by 19%, and potential status effects are reduced by 5%

SUMMARY
RPD + TI + UY gives a slight advantage in S/L damage and a disadvantage in F/C/E/N damage compared to TH + TI + UY. The 5% reduction in status effects in low level will not be noticeable.

PERSONAL EXPERIENCE
I my case running a Inv/Fire Tanker the low levels were about more damage to survive not more armor. Then I tried to max out my S/L resist and didn't have problems till the 30s. For this I used Unstoppable when F/C/E/N was thrown my way. TH was nice to have when since it stacked well with INV and Combat Jumping, and I took it before RPD. But I would never have taken either before level 24 since travel powers, stamina, and a decent set of attacks took preference.
This seems like more of an issue for Brutes or Scrappers of which I have no personal experience how well the switch of RPD for TH would be. My guess would be that this would be beneficial for defense capping with IO sets, but in the initial levels not so much since damage is king and both ATs have plenty of it.
Overall, this change does not seem needed. Invulnerability overall is fine once you understand its limitations and how to address those with IO sets.

My main issue is with End Management even with End Red in all attacks and toggles and IO end boosting bonuses it seems to become an issue. Low level before stamina it is still unpleasant, but that is another topic.

Good Lord, Castle already buffed Invul for the better. There really is no need to rant about fixing it anymore.
