To everyone that thinks the word Hybrid means you have talent choices that can cover another role in the raid (meh....if you have the appropriate gear) then by that same reasoning Holy Paladins, Priests, Monks are all hybrids because they can be Dps too, so they should suck at healing or be the same as Resto druids.
If you think that being an Hybrid means that you can heal and dps at the same time then no, we do not bring heals as healers, but as utility.
Druids bring Tranquillity -> utility
Mages bring Heroism / Bloodlust -> utility
Warlocks bring Healthstones -> if you didn't notice an healthstone heals as much as a Tranquillity
