Healbot is part of the learning curve. Clerics have incredible depth th D&D and in DDO, and healbotting is not a destination so much as a phase.
If the sole and entire goal for somebody who chooses to play a cleric is to heal, then I view them with
extreme contempt for wasting their resources, risking failed missions because of it, and not doing everything they can to help their party. If they're in that phase toward becoming an actual cleric, I'll hold my contempt.
A purely heal-specced cleric will have max wisdom in order to keep their SP as high as possible, and therefore also benefit from a very high DC, which brings their Symbols and Commands into real play, so short of laziness or ineptitude, there's no reason at all that even a purely heal-spec can't be a heal/CC. After that, they're just a maximize away from being OCC clerics. Finally cash and more build points will make them melees too.
I was a healbot once too, and it took me years -- first to realize what all is possible, and then a little more to play other classes to better understand their needs/strengths/weaknesses to perfect the art and become an actual "cleric".
Now I'm quite convinced that played to their potential, clerics are grossly over-powered compared to the other classes, who seem to me one-dimensional, and ultimately not much fun to play.
When things go badly, being the cleric is unrewarding, brutally expensive, and like a goalie, we get the brunt of the blame when we can't keep everybody on their feet,
BUT when our decisions, our "
sixth sense", and versatility save the day, ...well it's a pretty big rush that I've never felt with other classes.
