I know this is a bit far off still , but i'm curious. Will the AA's Headshot ( ranger ) , Asassinate ( Rogue ) , Decapitate ( Berzerker ) be like it was originally , with no limit on how many times they would trigger per min ? or will they be like they are on live now ? and work on boss fights ?
They will work like they do on live. This is true for almost all aa's (I think SK HT and Pally Lay on Hands are maybe the only exceptions?) on all progression servers.
