I get what you are saying, it takes a while to get used to. I came into the game expecting enmity-generating tank skills to be more powerful. The worst is when you have a black mage bombing big groups of enemies, you are pretty much forced to just spam flash over and over to keep up with that. Fewer targets are more relaxing, you can just watch the threat levels and hit your big moves on monsters you are close to losing, and provoke on ones you lost if it happens.
