Currently pain focusing guardian using MM version of ability - Suppress Pain. (its weaker). While its understandable why MM have weaker version of ability, cause its have pets. Pain focusing is healing focused set. And Guardian doesn't have any pets. So i think it should have Corruptors version of ability - Soothing Aura. Guardian have less of healing abilities than MM and Corr... But at least he should have a Corruptors version, so he can actually do some healing.
