It annoys me that as a melee carry Gangplank had to stop to cast every single one of his abilities.
What is the design or balance reason for this? Him stopping to cast his Q doesn't bother me too much, but for his W and E there is no reason for it at all.
Gangplank's E, his Raise Moral, is similar to many other abilities, a stats boosting cooldown, yet I know of no other abilities like it that forces the champion to stop, cast it for a short second, them keep running.

Its dangerous to run and shoot a gun at the same time "which assumes 3 of his skills"
The fruit eating skill shouldn't stop him though, just bad coding on riot's part
