Well, I'm not really arguing this from a realism standpoint, but from the standpoint of the games own logic. It just strikes me as weird when something that would normally stop a cast or any action at all, would really not stop an ability that needs to be channeled constantly. Collective Unconsciousness itself doesn't suggest it should render you immune to these things and yet it just kinda ignores it anyway. It's one thing for a game/book/etc. to break the rules of our reality, but breaking the rules of its own reality is another thing entirely.
