Gangplank Mid is Sleeper OP

Before I get into the analysis of the post, I just wanted to give some background info/qualifications about myself. I'm BestCritplankNA and today I just hit Gold 1 with a 64.1% win ratio on Gangplank mid. I have 64 games on Gangplank mid in ranked, but have about 160 total including normals. According to www.lolskill.net I am 27.2% better than the average Gangplank. You can find my op.gg here: http://na.op.gg/summoner/userName=BestCritplankNA

I made a post similar to this before where I compared Gangplank mid to pre-rework Nidalee, but at the time no one really liked it. But today I was browsing surrenderat20 and this post by Phreak made me want to give it another shot: http://boards.na.leagueoflegends.com/en/c/esports/aYUEYaY2-almost-everyone-wants-to-see-champion-diversity-in-lcs?comment=001400000001 . When talking about why champions get nerfed when played outside their main roles he says, "The changes to champions when they worked in certain lanes came from the gameplay impact of that lane. When Janna walked into lane, Pressed Q in the vague direction of the minions, and then immediately last hit the entire wave, that was an issue. When Lulu clicked "E" and then pressed "Q" twice, causing you to lose 50% of your health without it honestly being a real skill shot, that was the issue. When Annie's low level base damages and stun were so obnoxiously high you immediately lost any possible 2v2 fight bottom lane, that was the issue."

As a Gangplank mid main, I can tell you his gameplay impact on the lane is bullshit and should be added to Phreak's list. As soon as you buy you Statikk Shiv (first item), you literally crit people for 50% of their hp for the rest of the game. My largest crit in ranked was 1892 (one shot a Sona), and the best part is Parrrley is on a 4.75 second cd. If I was to describe his playstyle I would call it hit and run, similar to pre-rework Nidalee. You shoot a q and run away. No one can stop you from doing this either, because you have a free cleanse/heal so cc does nothing, and late game you literally can have over 590 movement speed. With ult slowing and granting vision of their entire team so you can catch up to them, there is nothing they can do to stop Gangplank from 2 shotting the enemy squishies. Not to mention you also grant 4320 gold worth of AD to your team.

It's also extremely difficult to shut him down, since you spend most of your money on crit and attack speed (which is normally wasted). If Gangplank is behind in items, he still crits you for 50% of your health. The only difference is that he crits less. If you start flask with a bunch of potions and the Alchemy mastery, you sustain through the harsh early game so it solves the problem of the bad early game, especially since you have a low cd ranged farming ability.

So, when I say Gangplank mid is bullshit I mean it. Historically I believe the highest average win rate ever was Kayle in Korea with 63% around the time the Runnans/Nashors build came out. For North America, it was preseason Warwick and Season 2 Ezreal with 60% win rates. If Gangplank mid can have a 64% win rate where he is countered by Morellonomicon and the popular solo que mids such as Zed, Fizz, Katarina, Syndra, and LeBlanc (I pick him into every counterpick listed here except Fizz), I can only imagine what it's like when those champions are not in the meta.

Discuss.
