The problem is in my title, right now the warriors -50% healing debuff (Which can be kept up 100%) and the summoner/scholar -50% healing debuff stack. What this means is someone with both will have 100% reduced healing, and take 0 heals. Since neither have a cooldown you essentially need to spam esuna nonstop to even have any chance of removing these.

This is breaking pvp. Making people completely unhealable? why even have a healer at that point.

-50% healing is understandable, -100% is not.
