Probably because a lot of healers, even ones who want 'healers should heal' style design, would be up for having Purgation from PVP in their kit for example. 'Big laser go ftwooom' is a cool feeling even for someone who 'doesn't want to do damage', like they could attach 'party wide regen' to it like it has in PVP and it'd be considered both a damage and healing tool. Does anyone who 'hates how healers are forced to do damage' have an issue with Pneuma's damage conditional?
