What would be the best cleric-based healer?
For what I've seen going 20 clr is not the best way.
Even a simple 19/1rng would have ~70 more positive spell power with 6 AP spent in DWS, giving up only 1 caster level (and capstone).
If you want to be less specialized you can even go 18/2 with divine might for some decent damage with either twf or implement bow (1 AP in ArA), remaining a very effective healer.
What build do you think will be the Ultimate Healbot?
