When I played a warforged tank I told the clerics not to heal me. I didn't take healers friend and knew healing me would be a complete waste of their sp. Instead I drank pots, alot of them. It was the most expensive character I've ever made. I'm not going to say they are right to refuse but healing warforged is very hard on the spell points of a cleric. Favored Souls might have the spell points to do it with no harm done. Casters are the most capable healers of warforged and it would be better all the way around if the cleric spent his spell points keeping up the caster that was keeping you up. Unfortunately a good majority of casters refuse (or forget) this role and I don't think I have ever seen anyone complain about that.
