A Small Change to GangPlank That Would Change Everything

Alright, so is always strong, and although his skill cap is very high it could be higher, infact gp could be WAY more interesting with only altering 1 mechanic on him. I am referring to the slow/ speed up barrel mechanics of his. You see this adds to the frustration of late game gp, a 90% slow and huge speed up give him what is by most defenitions a gap closer/ escape that only exists in late game, similar to jhin's crit speed up mechanic, but more drastic. I would suggest removing the slow and nerfing (or removing) the speed in place of a knock back mechanic. it wouldnt send a champ very far. The champ might not even be pushed to the original radius of the barrel, but (and here is the kicker) the knock up would stack so if i put 2 (or maybe I would need 3) barrels on top of each other and blew them up I might be able to send myself over walls.

The only thing I am not sure about is if it should affect allies, I dont think it should.

How will this scale? It will basicly scale with your cdr because the more barrels you can afford to put down the farther you can send yourself, so early game it wont change much, but late game gp can pull off some real plays.

What do you guys think??
