Please, don't try to sound smart. There's a role difference between tank, DPS, healer AND hybrid - especially in PvP.
DPS = strong damage, minor heals (for PvE survivability only)
Healers = strong healing, close to no DPS (for solo-leveling in PvE only)
Hybrids = decent damage, mediocre healing (I would say hybrids are more DPS-focused than heal-focused)
Tanks = they don't really fit in here because they're fucking overtuned at low level PvP but useless in end game, they should have less damage than DPS but way more mitigation/survivability and also only minor heals (like Victory Rush)
Everything past that is overtuned, so if you crit 800 Ferocious Bites as Resto druid, 400s with Denounce as a Holy paladin or get 250 Penance ticks+250 Smites+200 Holy Fire as Disc priest, yes, then there's something wrong.
