Gangplank Deserves a Dash

I mean, he's a pirate king. Pirates are raiders, meaning they go in, do some damage, and then get out of there. Unfortunately for GP, his outdated kit doesn't allow for such escapes. All he can do right now is boost his movement speed and eat some oranges if he gets cc'd. The only form of cc he has is slows from his passive and ult. Maybe attach the dash (I imagine it as a somersault) to his W (and reduce its healing to compensate, making it more of an escape mechanic than sustain in a fight.) That way his combo becomes more straightforward: E to engage, do some damage (Qs and AAs), then W to escape (or chase and finish them off) and let the DOT from his passive (which also needs to be buffed or reworked into something else) chunk them down for more. Despite the rambling towards the end, what are your thoughts on the subject? Does he even need a dash? How would it be worked into his kit/ what needs to be changed or removed?
