Is 1-shotting someone like that, in any situtation, OK to you?
No, was one shoting in df by mage during whole cata ok? Was one shoting by rogue in one smokebomb during s11 ok? Also no. How is warrior different? They actually need luck to get 5 stacks in arena game, I told that before, Reckful streams for hours every day and as far as I know he one shoted one guy. That doesn't happen every game or even every day. Do you see what mages are doing atm? They actually are able to drop people in one df every single time they cast it.
Give back gag order glyph and then nerf burst dmg. Without gag order, dmg must stay cause warrior will be useless again.
You do know that for example the mages (who you are so bitter to) burst is WAY easier to counter than warriors random 1-shot? You have alot of time to react on a mage whos red and popped everything he has. When warrior does this, you simply can't react fast enough, as the best of players have proven in their streams or in Youtube.
Get over your grudge towards casters and admit that warriors are more troublesome now than any casters has been.
