Tanks Advantage and Deficiencies

[Reynhart]

Yeah best AoE DPS is with no contest WAR. DRK is no match vs. Decimate/Steel Cyclone and Overpower spam.

Well, technically, spamming Overpower do more damage on several mobs than Steel Cyclone or Decimate, since you can't "spam" it.
While building Wrath stacks, you will only hit one mob.

So it's basically Overpower vs Unleash+Salted Earth
And on that, DRK wins

Not necessarily, if you know when a wave of adds will spawn like in A2 you can have 5 stacks of wrath ready with an infuriate followup.
Warrior also have a dps stance were they are able to get 25% additional damage(20% from Maim and 5% from Deliverance) unlike Dark Knight that only gets 15% damage increase from Darkside.
And again I cannot stress enough how all this scales with Berserk when used correctly.

So it's not so cut and dried.
