I, personally, don't have a problem with healer's not dpsing. It doesn't matter if contributing minor amounts of damage is the optimal way to play. The simple fact is the healer role was not designed with the intention of them having to contribute to damage so it doesn't bother me if all they do is heal, even in harder content. The idea that people expect them to dps as well as heal is just wrong to me. I'm not bashing anyone but to get upset if a healer doesn't dps seems stupid considering dps isn't a game mandated requirement for healers.
