I'm a new player looking to play as a healer since I usually go for the support role in multiplayer games, but I'm torn between which race and class I should be picking.

I'm considering choosing paladin, but I don't know which race would be more suited or how difficult the class really is. I was also thinking about asking how fun it is, but then again, fun is pretty subjective, isn't it? Can I even level up as a healer on my own? Any advice would be greatly appreciated.
