It would be great if clerics had a purify upgrade that would caste a group-wide effect in the same range as the buffs or chromatic heals. Even at lvl150 I can't caste purify on a whole party fast enough and someone dies and can't be ressed in time before a boss dies or something because I'm busy trying to keep the rest of the party alive. An AoE Purify would help tremendously with that common struggle.
