Well if this is how things are going to be, I can't wait to see NiM TFB: Operator IX only casts rainbow color deletion protocol so anyone can cleanse it.
LoL that fight is ****ed up already. Let's say a purple person get purple deletion. Now you have two options:
1. Let the other purple person run in and get rid of both the debuffs, meaning you have no left for the next time purple deletion happens.
2. Say goodbye to the first purple person as their own debuff will not protect them but at least you will have the second debuff ready for the next purple deletion.
