Should Counter Buffs Be Cleansers?

As for the others, no adding a buff/debuff shouldn't dispel/cleanse its opposite. It already negates it while it's there. If you have health up for two turns, then acquiring health down for one turn effectively negates it for one turn, then when health down wears off you get the benefits of your buff for one turn. It makes the length of buffs/debuffs matter.

This is the biggest reason not to go along with what the OP has proposed in my opinion.

Rex gives Tenacity up for 3 turns. Most people that inflict tenacity down do not do so for 3 turns. I am finding that debuffs in general seem to last one turn less than their opposite buffs, which makes the turn difference almost always relevant.
