Cho's Q and W have always felt very wonky to me. On his Q, Cho's death cancels the damage / CC effects whereas many similar skills still carry on after death. On his W, the actual range seems to extend slightly further than the tooltip would suggest, though the cone seems to be smaller. There's also a short delay between using the skill and the silence / damage taking place.
For the immobile mage update, even if Cho is not being changed, could we look at the spaghetti code behind some of his skills?
