WoW does things that makes healing rewarding and interesting. It also varies how healers heal through their mechanics: HoTs, Off-Tank Healing, Barriers, Direct Healing, Chain Heals, etc.I think I'm just warped by my time playing WoW. The idea of not needing healing (and having it baked into the game design assumptions) is just...flawed to me at this point.
I enjoy playing healers, or at least a class with healing abilities on hand, because my own playstyle in MMOs and TTRPGs often tends towards support and tactical defense. In D&D, I have played a lot of clerics and druids in my time.
This is what 4e tried to do with roles: Defender, Striker, Leader, and Controller. But you could also do a similar setup in 4e too entirely with martials, which was the great thing about it.Fighter/Barb Front Liner
This should just be a basic assumption. The whole 'bring 4 Fighters, YOLO!' kind of open design is just way too far for me.
Fighter/Barb Front Liner: 4e Fighter
Thief/Trap Guy: 4e Rogue
Healer: 4e Warlord
Ranged Damage: 4e Ranger
It's really been the only edition that made me love playing non-magical martial characters.
