Had the same with a healer when I was tanking. I had to actually tell them how to Swiftcast + Raise, never mind the associated troubles of being barely healed at deaths door multiple times.

To answer the OP though, Arcanist without a doubt. It's basically 2 jobs for one potion. Two different roles as well, so you can enjoy healing and DPS both. No other job offers this diversity.
