There is a bug with Draven and the new Gankplank where Draven can basic attack off of Gankplank's(ally) barrels and gets unlimited q stacks. This was first shown on a twitch stream. Not sure if its a bug, buts it's op af. Reddit pls.

BeatzBoyFTW2 votesGP's barrels are treated as a minion, or a kind of Kalista's W or Zyra's plants, since those barrels still grants golds. Pretty sure Draven can still ricochets his Q onto his barrels for his passive stacks.
EDIT: Wait, nvm. Didn't read the (ally) part. That's weird. You mean both Draven & GP are on the same team, and Draven happens to get free gold off of his own teammate's barrels?
AmazingBeaver1 votesHave you actually read what the guy wrote he bounce of the ally's GP barrels hows that normal u twat
BeatzBoyFTW2 votesI have already edited before you posted lol, you twit.
AmazingBeaver1 votesWhy you didn't opened your eyes in 1st place you wanker , and reed the whole damn thing you cunt hole
BeatzBoyFTW2 votesBecause I was afraid this thread would turned out to be a similar "thresh & relic bug" or "Darius E flash bug" type of thing, so I got a lil lazy in reading, you dope.
AmazingBeaver1 votesSO your too lazy to reed but not too lazy to try to look smart , bitch this shit makes no sense .
BeatzBoyFTW2 votesSo I had a rough day and feeling tired, cant a man take a break T.T And chill your titties (or PMS, w/e), at least I didnt swear or call Op dumb and stuff.
AmazingBeaver1 votesOnce again you are too tired to reed but not too tiered to write , bruh ur dumb af
BeatzBoyFTW2 votesAnd you're too hyped to be calling people dumb over simple mistakes & then makes lousy spellings. Bruh, u drunk af.
HoldYourDongers1 votesoh yea and its also op cuz the barrels dont break or anything...they just stand there. So literally gankplank can set up 3 barrels for a draven to stack up x.x
HoldYourDongers1 votesYes the Draven and Gankplank are on same teams. I wish i got video of it, but im pretty sure its easy to do on a custom game with a friend.
BeatzBoyFTW1 votesMy best bet for you is to try take a video of it, or a few screenshots, and send them directly to Riot Support. Here at Boards, you shouldn't get your hopes too high up as they rarely reply you.
