I would disagree too but it's sort of a personal preference. I've been messing around with Divine Healing a bit in the last few months and it was really just a dumping ground for enhancement points. The big difference really is, it didn't really have the kind of benefit you'd need as an end-game ability to justify the costs.
So, in my opinion, absolutely NO as an end game ability, however, play your character the way you want to play it. I can see how it might have value to different styles; I am, after all, goofing off with it myself. I'm about to reincarnate my only cleric soon anyways and it's probably permanently gone at that point.
