I realized recently that I really enjoy healing, and I enjoy a good amount of complexity in a class. So I've decided that I either want to pick up SCH or AST.

As of right now I'm leveling THM for Swiftcast and then CNJ or Stoneskin. So I have a little bit of time before I pick. (I realize I could just switch whenever but I'm stubborn)

I know that either is good for end game content, but which is more fun to play? I would like your opinions on the matter. So feel free to elaborate as much as you like on why you prefer one over the other.
