My best guess for 7.0 is that it's gonna be a crazy like 3 shot kill burst meta in 7.0. Mostly cuz classes are losing dcds and then I'm sure bioware as per tradition will create a gear grind and introduce a new augment tier. So higher dmg higher stats less dcds. Seems like a bad combo to me. A couple decent players playing burst spec can already do a ton of dmg and blow ppl up in 6.0, gonna be wild in 7.0.
