I'm okay with this explaination, but for the sake of UI consistency, can we take the chann-err... "progress" bar off when casting it? It drives me absolutely nutty that it has what looks exactly like a channel bar but behaves different from a channel. And I say that from an Ezreal player perspective. When I see the bar looking like it's channeling and it goes off regardless, then try to translate that over to someone with the same (from a UI standpoint) thing i.e. Fiddlesticks/Nunu, it is frustrating to see that they behave differently. Not to mention that for newer players, I'm sure this is confusing as hell.
