1 MAJOR thing
hero stats IS NOT ALWAYS 100% acc so i'd use it more as a guide
as for misses against COTs i'd have to agree that the miss's are higher than against any other groups/mobs even taking into account the COTs acc debuff's i have a lvl 40 DM/FA and even kicking in firey embrace and soul drain my 1 SO slotted brawl hits MORE OFTEN than any other of my attacks, dunno what it is but maybe cov way the COTs acc debuff is higher than the ones coh way, either way i'd rather cut my left testicle off that go against high lvl COTs
ok reading through all the posts in this thread most complains about brute acc- seem to be centered round COTs, someoen do us all a fav, 1 see if coh way wether the COT acc debuffs stack, also to what degree they debuffing then see cov way just how many stakc and also again to what degree, got feeling it maybe case that cov way that COTs acc debuffs more powerful and/or stack more :/ 
Having originally posted in the thread listed by Filth I still maintain that yes there is a problem with Brute acc'
I appriciate the posters who have pointed out that because brutes have a faster attack chain they "appear" to miss more, but I think there is a genuine problem here.
In my lower lvl brute days I ended up being faceplanted by a same level Longbow rifleman in a 1 on 1 fight simply because I missed that many attacks I ran out of End' and became a sitting duck.
Unfortunately as Bridger made clear in the above mentioned thread the devs won't even look at the problem untill someone produces "tens of thousands" of test results with herostats
Sorry for the rant but I genuinely believe there is a problem, perhaps only on certain powersets or toggle power combinations ? unfortunately the general players do not have the time or facilities to investigate this. Thus we
just have to live with it.
But it seems more than a coincidence to me that every so often a new OP will ask this question and only when their playing brutes 
Tbh i don't have any major concerns with accuracy except when i have to fight CoT. I can fight +2/3 level critters on my DArk/DArk brute with ease.
Then i get a CoT mission, and oh boy does my face turn red. If I fight EQUAL level nerva demons and im as good as dead, i have no way of defending against they're 3-4 -acc debuffing attacks/heals and the second a D/D brute is -acc i cannot heal, dark consumption, hit with basic smash attacks, use my soul drain (buildup/Powerup move) Because they're all based on accuracy. all i can do is die, and hope that my self res keeps the damn demons stunned for long enough so that i can kill them before they start debuffing me all over again.
I mean seriously, what genious makes matching 'theme' based powersets which are so heavily reliant upon accuracy have a +acc move which requires u to have the damn accuracy increase before u can use it?
I said earlier that other mobs other than CoT aren't really a problem, thats not entirely true, i just cant remember which mobs i struggle with, but any which use -acc and especially COT who (whilst being strong against the melee smash dmg in the first place) have the ability to spam u with -acc making me nothing more than a high level Fan, maybe i'll get lucky next time and they'll catch a cold and drop dead whilst im on my way to the f***ing hospital!
