I have not won a single GP game since last patch.
I'm really burnt out by now. You are way, WAY too vulnerable as GP now and I am begging for some sort of revert or new playstyle to help him. I'm a pretty good GP player, I swear I'm not just an angry kid who is annoyed he can't win without exerting effort. No part of Gangplank feels fun or rewarding any more, it's just an agonizing slope to losing because you are so helpless in any lane as far as I can tell. You can't poke, you can't really farm without getting all in killed, you can't escape ganks because your barrels no longer can ward - all the strength has been pulled out such that there's no late game to get to and no scaling into cheaper, earlier builds. He's an honest to goodness dead champion, not even a 'late game' champion. You'll never eek by to late game when any top laner can 80% you in a standard trade.
Yell at me if you want and tell me I'm wrong, whatever. I just am saying from experience my very favorite champion since season 4 is now unplayable in his current state.
