I seem to lose 4 out of every 5 arena games whether it's 2s or 3s on my Glad Warrior due to the pathetic pressure put out. I was 2k the last few seasons (nothing amazing I know) but for some reason, I can't kill anything ever and I can't think of what the warrior class offers over say a DK, Ret, or Feral. The classes listed all heal waaay more, output 1.5x-2x my damage and arguably have better survivability over time (once our Shield Wall/LS is down, what then?).
On my feral, I've went on streaks where I've won 10+ games in a row easily and that's when playing with a freaking WARLOCK. Besides DKs, no other class can out DPS me and against warriors? I eat them alive in all aspects. I don't think that's saying Ferals are strong but that Glad Warriors are seriously nowhere near powerful as they're hyped up to be.
The only time I might kill someone is during a Bloodbath + Shield Charge + Shield Slam with Heroic Strikes during each global and that's if it's against a douple DPS comp. If it's warrior/healer vs any class/healer, 90% of the time I'm fucked. I've been bouncing between Heavy Repercussions and Unyielding Strikes to see which is best and I think it's up to your personal playstyle.
My warrior is almost full iLvl 620 so I'm hoping like every season, we get much better with gear scaling.
