Orcs – discussion about the race.

Well, that's going too far. What's wrong with Blood Fury? And if you combine it with what you're suggesting, it would be too overpowered. Although I agree that you can mess up with the dampening effect, and you don't always want to dedicate an entire skill to it. But I guess there's nothing you can do about it. Although the idea of a shout that disrupts magic is pretty good.
