I don't see any issue with warriors having short term big dps boosts that have a negative to tanking. Why not? They are supposed to be the masters of weapons and gives them something to do when they aren't tanking. I am not sure why anyone would argue that. Something that every 10 mins or so, they get a big boost for 1 min or so but with a mitigation hit so they cant use it while tanking. That way it could be tuned that sk are top sustained, war are top burst and pallys are tops against undead. In the end, its not going to be huge anyway, because we are tanks, not dps and will never match dps classes by any stretch.
