We are progging TTT on PS/NA. Last night we had our first run post patch. Unfortunately, it seems that the "efficient purge" skill is broken in vHoF. We've seen posts on this in some of our discords as well. We are using purge on the first boss to cleanse the poison debuff placed by the spheres around the room. Instead of purging the debuff from players, purge was removing debuffs from enemies. Self purges, such as ritual from templars, the netch from a warden, and expunge and modify on a cro all remove the poison debuff. It is only the "purge" skill that is broken. This is a new issue post-patch.
