I think Four Elements Monk is the closest, but it's not really the same either. Since that's probably the least liked of the Monk subclasses I'd say it's probably nowhere as ridiculously powerful as kineticists are either
Fair. I guess I was thinking of the 3.5E warlock, but in 5E its definitely the Four Elements Monk. But even there the similarity is mostly in flavor rather than power and ability.
