I find there is just to much rage, this is really a game. There are people who act like idiots yes, but it is no fun to just "let them die" to learn. What I do is ask them, well what do YOU want me to do? If they say spam AoE hate gen the whole time they can see my tp/mp drain and become unable to do ANY hate gen and wipe the party. Gives them a good guilt trip that the first time it was just them, and when the tank tries to correct its a wipe.

Typically I will tomahawk a mob that gets away, usually turning it around long enough for an overpower/flash and regain it. Also swapping to it for a quick hate rotation to make sure it doesn't leave and move to the next one. Doing this I can typically hand keeping hate from spammy dps, most freak out when they see the mob turn, if your lucky they will look for the mob everyone else is attacking and refocus.
