So far the best hate holders are Cure III and sac III I believe, but what you need to make sure is that no one is attacking or healing for the first minute or so, only you heal yourself to get a hate head start. Also stress that your members use there -hate abilities and their hate transfering abilities to get more hate on you. (Lancer has colusion that transfers all hate from next attack to the target between the lancer and the lancers target) basically we have to cast it on the mob and then get behind the tank and use a weapon skill. I think Archer has a similar skill to transfer hate, also there are many traits that lower hate generation as well.
