Once you get enough set slots and bonuses its skippable... but I would never go without it when using simple IO's, myself
Mmmm, that wasn't exactly what you told me yesterday, but it is an improvement from your previous position in the discussion 
BUT (
i love those BUTs) I still think it's a must have in a pve IO'd build, even letting aside the HUGE ToH buff it provides, it's just worth only for the chance of build up unique, and if that's still not enough (altho having an extra chance of buil up permanently on every single attack is quite a bit if you ask me)add to that +percep in case you are not playing a secondary with +percep, and finally, because for pve, you DO want energy torrent, and FA is way more useful than conserve power on a full IO'd scrapper build -game, set and match- ^^
Ein? 
I agree with you on the IO'd build part.... which wasn't the question btw, but anyway (I love those but anyways) it is an interesting input.-
Cheers 
You could probably skip it these days with appropriate sets. Some of the to hit numbers I can get out of Mids even for toons without FA mean that they are only ever going to miss on a 'fumble'.
With Focus Chi and FA, Flitz has accuracy numbers in the 250-300% range for most of his attacks and a massive 375% for Cobra Strike. However, I am unlikely to drop FA as I have it 6 slotted with Gaussian's Synchronized Fire Control for the extra def, recovery and damage.

VIGILANCE Captain Caledonia 20 - Yeah, I made toons on the French server coz we only had 4 back then (might have to transfer/recreate them on one of the US servers)
..and many more!
That is a helpful set, but can be slotted on BU, what makes me think is the perma chance for build up...
No perma chance of another BU if you slot it on BU sadly 
There are too many variables in what you can find in PVE. I went years on my claws without foc acc and never found it necessary but after transferring to another server with her and coming across people who don't operate the same way its been on and off useful. As in don't need it versus one enemy but then do need it for another. Expect differences of opinion but the words "must have" is balls unless your talking about yourself.

Thing is, as per Mid's, that enhancement grants a 20% ToHit with a 5% chance of activation. Is it worth a 20% ToHit if you already have FA?
Prolly more helpful in Tactics tbh.-

Although personally, on the one scrapper I have that SIO it's in blinding feint instead.
Hi,
About the Gaussian chance for BU IO in FA, it is almost a waste of slot as per my personnal experience ( 5% chance to fire of is a bit too low IMO ).
It is also the general consensus on the US board.
To be honest even before IOs, I found 2 Accuracy SOs in an attack was enough. Even now with the IO sets out and bonuses, I don't think Focused Accuracy is a must. It is a nice power to have, but you can get away with not using it without compromising your build.

Aha, didn't see that on Mid's but obviously that's better, still for me doesn't justify FA.

Got this on my MA/SR scrapper and i have no issues with missing when its not running so like you i could easily skip it.
BUT (we all love this word really) i do plan on 6 slotting it (the set with the chance to build up, cant remember the name at mo) since the build up effect does become quite noticeable and the extra defence it gives me via set bonuses is VERY nice.
I guess it all comes down to endurance management and attack chains. My attack chain is constant and endurance problems are non existant so it enables me to easily keep this power on all the time.
Stupid long post almost over ( 
)but basically its worth the choice just for the defence set bonuses + the chance for build up. But i do have slots to spare regarding that statement.
@Damz Find me on the global channel Union Chat. One of the best "chat channels" ingame!
FA is sure nice to have but I definitely think it's overkill for the PvE game. I suppose a large part of the decision comes down to whether or not you can justify the end usage.
As you know NM, all my scrappers are /DA and /DA probably stands to gain the most from FA, especially DM/DA, what with the to hit check on Dark Regen, Cloak of Fear, Soul Drain and so. But even with all that I'm quite happily running without it on both my DM/DA and my Kat/DA.
For me, if taking body mastery epic, FA is less useful than either conserve power or energy torrent. I probably even got moe use out of laser beams...
Ok, let me try put this together on a coherent way. I was earlier on discussing with a mate about Focused Accuracy, I always thought it was a must for any scrapper, but radically changed my mind (we're talking pure PvE here) since inventions came out.
Basically I have respecced out Focused Accuracy from all my lvl 50 scrappers and I don't miss it at all for PvE, of course, any other scrapper with Muntions or Dark Mastery could have told me that months ago (what a Sherlock I am).
Anyway, thing is, in my opinion, with the available accuracy bonuses from sets, plus the set slotting itself which favours accuracy (any melee set enhances over 60% accuracy while on SO's usual slotting we were happy with 33% or 66% if 2 acc SO's) seems to do fine for PvE. My mate, who knows this game far better than me and has been playing CoX forever, disagrees with me and maintains that Focused Accuracy is needed for PvE.
I know ToHitBuff IS NOT Accuracy buff, and I am perfectly aware that Focused Accuracy IS a great power choice, but I'd like to see some opinions regarding this subject.
Do you feel Focused Accuracy is a must for PvE nowadays or do you think it can be compensated without major problem with set slotting / set bonuses?
