A lot of good changes, but i think the balance team are making a HUGE misstep in giving almost all classes Alac and Quickness!
Scourge does not need alac, and should keep what makes it unique. Yes its OP in some areas, fix those please.
I think a much better design direction would be for some classes/specs to be masters of some boons. And not giving any class mastery over ALL boons . I would love for scourge to be a Barrier and possibly Stability focused spec,, or whatever really, just dont make everything the same. I know Anet wants "Bring the Player, Not the Class", but for that to be functionally possible, all classes need to be mechanically the same, with different fluff, and that dont sound fun.
Please reconsider this direction to give something unique and interesting to classes. If Alac and quickness are so important to the game, then you need to fix those boons instead of putting them on every class.
