Warrior is either amazing or terrible. NEVER let yourself be at the front of the mob so that you are targeted first. You need to be able to get off your charge. I roll DW fury regardless of target since bloodthirst is off AP rather than wep dmg. IMO if you are fighting in a full scale mid battle, go for the squishies and good hunters. Prioritize. On a non-bubbled clothy, i do 500-800 dmg in the initial charge stun. It varies so much because I have 4 hits landing (and each has a chance to crit) in that 1 second: the 2 auto attacks, bloodthirst, and if i have enough leftover rage, which i usually do, heroic strike.
I have bloodthirst and HS macro'ed together so i only have so whack 1 button. Remember, during that 1 sec they can't dodge, block or parry.
Above all, choose your fights.
My armory for hit stacking (within reason) is in sig. (Omegå)
