Other Elite spec heal
Engi can already be a pretty heavy healer…was better back then with healing bombs but still engineers can\could pull off a dedicated healing build without much issues..even more so with the upcoming balance patch where the healing turret scales with healing power. Also you got the e-gun with its group condi cleanse and heal and another 2 water fields to your disposal and traits to deal pretty good with conditions on you and your team…so blast away.
Ele… obvios, dont need to explain anything there
Guard.. well obvios too…
War and thief are from a design standpoint more fighters then medics
Necro.. ehhh.. sorta does the opposide of helping people to life…but there are wonderfull ways to play with conditions and traits to keep team members from loosing health in downed state and even porting them over to you when in downed state..so thats that
Revenant got an entire legend based arround healing and avoiding incoming damage alone
Mesmer… ehh.. dunno much what to do there but im sure somebody does it in some way shape or form and pulls it off.
and the ranger.. who now with the druid got the magnum opus of healing to their disposal… so yea there ARE healers in game if you want to make a healer on other classes but rangers.
Thieves elite spec is based on dodging, guardians one is based on ranged combat, engies is based on control (or whatever it is), ect. Not everyone is going to get the same stuff at once.
But yea, seems likely there will be a dedicated healing spec for each class eventually. Might take 5 years for it to happen, but its better than all 9 classes getting a healing spec one expansion, and everyone getting a control spec the next one, and so on.
If they want to have the holy trinity required for raiding without people having to wait to have specific classes to do them, they are going to have to give every class a tank and heal spec.
