Have played some PvP now, and bought some PvP gear pieces and made a gear set that consist of only Crit+Det.

But i have read on forums that there is an accuracy cap that i need to hit, some say one accessory is enough and some say 2, but i couldn't find any who have tested this. So is there anyone who have tested if it is enough with one that gives me 378 acc, or do i need two so i get 402 acc?

I can't find out if Crit is better than Det either, i assume so but would like confirmation. If i need 2 accessories with Acc, should those have Crit or Det in them?
