I have lvl 70 shaman and lvl 42 paladin! Shamans got reincarnation and Paladins have Divine Intervention! Well
1. Reincarnation - shaman rezz himself with 20% (40%) health and mana, and can rezz everyone, or u can use it in fight and save party/raid, and u can use it alone, after u died.
2. Divine Intervention - u make other rezzer invurnerable for few min, kill urself, and make other rezzer rezz, so u need to be alive, and other rezzer has to be alive, and u have to be sure that everyone will die or its just waste. And u cant have any other use of it!
Reincarnation is just OP comparing DI. So what do u think if they changed DI to something like this
Divine Intervention - Paladin kills himself but tries to rezz other player! When player accept rezz he get 40% mana/health! i think this should be fair.
