I've been doing the NMs in parties of 2 and 3 R50's, and the hate balance there seems to be better than at R50 NMs. If I overnuke, I'll rip hate on a R30 NM pretty easily. Anywhere else I can pretty much chain heal and chain nuke with no repercussion, and I don't have the archer traits and abilities yet.

So long as I don't spam profundity blood rite and elemental (or is it dark?) seal. Enhancements are by far the number one reason a mage gets hit, even more common than tanks dying.
