there is literally another warrior on alliance in the same BG (very well geared, he in fact inspired me to make a WW war).
if you look at the score page, i outperformed him by quite a bit, a bit more dmg, way more healing, way more objectives. his teammates were doing much better than my teammates too (just look at the numbers, they don't lie). keep in mind i am very new to the class too and don't have weakaura set up yet.
in fact, in one instance, greenwhelp armor prevented me from getting stunlocked by an ally rogue, and i was able to ignore the sleeping rogue and charge to an alliance player near a cart that was about to be capped, i took it with another horde player (i think warlock).
i think some people here don't play the bracket enough to comment on this matter. (not dre, he just genuinely disagrees with me)
back on topic, i think whatever weapon you use (i suggest singing + pulv), make sure you pick up these. (i am working on that now). i believe these are becoming BiS for warriors in the current meta.
