It's like the silence effect in oblivion! You don't need to speak to cast spells, and on here, it's not like you are exausted. It's the dragonborn!!! You should not have a cooldown in skyrim! it's not like you are a normal person. I know it's for the sake of not making things too easy, but give me an option, or at least a amulet, robe, lesser power! Or even a dadric quest!!!
