Cleansing Revival, the blue slottable cp, entirely disables dot builds from being useful in cp enabled pvp and needs to be limited in the number of purges it does. A full dot build or a primary dot build are disabled since once in execute all their damage is now gone and need more than the 24 seconds that its cooldown is to reapply all the status effects dots etc etc all while now the fully non debuffed target can just spam heal back to full with little incoming damage.

A single slottable cp shouldn't disable a play style, its unfun and uninteractive, sure it could purge like 12 things and even then it hurts when execute but doesn't drop damage to literally 0. Currently with a dot built the only thing that can be done to counter this is use a different built or meta approved play style
