Also, one thing you need to be aware of is that the initial action on a mob will not increase your hate on the mob. It will only claim the mob for your party. This is why you don't want to start a fight with provoke - you want to do some sort of other hostile action first, like attack, throw, disorient, etc to claim the mob first, then taunt, provoke, etc.

Also, for some reason, self-buffs like Raging Strike, Ferocity, Blind Side, Profundity, Blood Rite, Dark Seal, etc cause a lot of hate. Use those too if you have space on your action bar.
