There's two sides of debates. You give your opinion, and someone can either agree or disagree with your opinion. We agreed that WHm is a fine healer, but we're in a disagreement that it's fine to stay like this as long as they can keep people up.
There's more to every other healer than just healing, and there should be more to a WHM too, unless they buff the strength of their heals so much their heals are hands down the best, which it isn't atm.
