Seems there is an issue with enmity slightly different than what I posted about with TP draining.
I can AOE a group of mobs now and if a mage in my party even does a cure 2, he will pull hate instantly.. This is after I have done 600 damage to that mob and should have pretty solid enmity.
A cure 3 shouldn't even take hate off me after doing that, especially with intimidation on and using warmonger.

It's never the mob I am directly engaging that attacks the mages, from what I see though. It's always one of the links. Still, the links have taken the same AOE damage that the main target has taken and should definitely not be attacking our mages.
Also when this happens it can be impossible to take emnity back and the mages die frequently due to it.
