All the jobs have the two shared self healing skills, but of the job specific abilities, I'd have to say between monk or reaper. If arcane crest was still 100 potency then definitely reaper, but they nerfed that to 50. Monks 3 stacks of riddle of earth on a relatively short cooldown is pretty wild. The stacks are a hold over for when it used to give an additional effect of ignoring positionals and I'll be shocked if they still have the 3 stacks in 7.0.
