I'd prefer neither of those to be true healers. I want to see things that cut between the roles, the sooner the better. I know full well what changes would be necessary, systemically and on the communities part, for matchmaking, but I think it's honestly worth it.

Barring that, whichever is the more original and can remain viable while being less of a "standard healer", discounting also singular gimmick sets such as Cards or WHM/SCH style-swap abilities.
