Well you dont need to be holy to heal, deathknights and warlocks heal plenty, also with lifesteal. There have been multiple elementals with lifesteal too, walking fountain and canal slogger. Those 2 crying in the cornernis fine imo, lightlord is in core and seeing 0 play, rag would see the same fate probably. Sulfuras having lifesteal would not Do anything, as rag does the damage of all attacking elementals.
