I think your numbers are off.

I'm "fairly" sure flash and voke are both 500 emnity. flatbade combo is x4.5 and rampart i thought was 240 per person buffed with hate more than zero and divided amoungst the number of actively engaged mobs.

divine viel doesn't generate hate and if i recall any emnity from the divine regen is procced onto whoever triggered it. i.e the whm/brd that cast the cure and not the paladin.

don't have any supporting evidence of these numbers though hence why i only said "fairly"
