[AntibioTsu]

I don't like this idea.

Warlocks aren't supposed to bash doors, but instead crowd control and kill incoming enemies. It's better to let warriors keep the door-knocking job, otherwise they lose only of their few (maybe only?) roles.

Besides, if there are no enemies to kill then the Warlock can always provide mana to the warriors and archers that need it, so I think it's unnecessary to allow spell casting on the door.
