But there is no scenario at all in this game where going in to any content effects the Emnity of actions. It's all set in to the actions ready to be used when they become available, they are not changed on entering an instance. Managing aggo is a major mech in the game and so it would teach nothing if the game itself managed it for you, this isn't WoW. A 600 potency Foul (or whatever the number is) is going to pull aggro more than a two hit combo from a tank, because that's what damage does. Healing also can pull as well, so that's another role of jobs to consider balancing.

I'm not saying that it's a bad idea, but it's definitely not as easy as what you think it is otherwise it would implemented.
