Was in ToV this last evening, and were killing Lord Koi`Doiken.
After we killed him, his dot was ticking so i did what i always do, i cast Radiant Cure 3, which in the past has healed the dot just fine. Well by all apperances it healed it, no debuff on our bars or anything but it was still ticking away, for the full duration.
Not sure if this is an issue with dispells/cures in general or if its an issue with this particular AA, im going to play around with other Cure effects and see if the problem persists.
