Vael - Less HP.
Broodlord - MS less frequently. Seemed to hit less hard as well.
Ebonroc - Shadow of Ebonroc going off less ?
Chromaggus - Seemed the same.
Nef - Shadow Flame entire raid at Phase 2 landing to stop OOC so I guess that's a buff.
Summoning this green dragon in moonglade tonight should be good
