actually from the testing Ive managed to do, and the other rogue in my guild who has also been testing can back me up here, we've come to the agreement that:
As assassination the enchants/flasks/food which are giving the best performance is actually versatility
ok so, the class seems to be rather undertuned atm...or at least the lv 100 talents do and the
premade pvp gear has stats on it which go together about aswel as toothpaste and orange juice
but over around 2 solid hours of testing (all 3 specs) thats what we discovered. Take from it what you will
I highly doubt it'll stay like that, and ofc there are still class balance issues ongoing.
