Riot why do you never do anything with Gangplank?

Now, I know he is getting a rework but that was announced almost 2 years ago and the last major balance change to him was in December of 2012. Some of you may say though that the cannon changes on the PBE will make him better, yet all this does is fix something that should have been done a long time ago.

The major question I have for you is why you never buff Gangplank, and don't make the remake an answer since that probably won't be launched until next year or so. All you would have to make him at least decent is a bit more damage on the passive (it is good early game but goes unnoticed late) and some the removal of animation locks on his w and e (atleast the one on his e, since with how its primary focus is about chasing, it can't fulfill that since you never want to purposely stun yourself while chasing people)
