Q range: 625, 25 units longer than your Vault range
Gangplank's Skill Max Order: Q → E → W
Level 1: Be cautious of Level 1 GP. Do not leash in this matchup because a good Gangplank will get prio over you if you leash. Conduct Quinn Cheese level 1, you win the trade because he won't have grasp and you get 2 harrier marks, but don't let him auto you because this gives him a burst of movement speed and true damage. His Q is 5 second CD, so do a short trade for 3 seconds before backing out of his Q range. After the first trade, don't walk into GP's Q range until your E is back up (its 25 units longer range than your E). His Q now will have Grasp procs after the first trade, which do a lot of damage. When your E comes back up, walk into range of him and then Auto-E-Auto and run him down, you will win the trade because he only gets 1 empowered Q on you. Ideally, walk up when your passive is about to come back to get 2 harrier marks on him. Fight him when your passive is about 2 seconds on CD so it marks him after you consume the vault harrier auto. Never walk into GP range unless your E is up because he will always get a free empowered Q on you if you do.
Level 2: He will start either E or W (if he's low), but usually his barrels. When he drops his barrels, the best mechanic is to vault GP the second he explodes his barrel. By doing this, your Vault will juke his barrel damage if you master this interaction. Here's a clip of me doing it against Solarbacca, the Rank 1 GP. GP has the edge in lane phase, so that's why I like fleet because if you take a bad trade without some sustain (fleet or taste of blood, for example), then he can poke you out of lane with ease.
Level 3-5: Now he has W. Gangplank W doesn't remove nearsight or ignite, and it is a long cooldown. If you bait him to use this, you have a long window to aim for a kill. Be cautious of dives because GPs like to stay low and bait a dive by using W last second. If he has W up, ignite him before diving so he doesn't heal as much
Level 6: His R is good for him all-ining you.
I recommend Fleet for this match-up, though PTA is better to punish GP in lane.
Electrocute is good too, but you must be better than GP to succeed with this.
If you take bad trades with Electrocute or PTA, you will have a tough laning phase.
The choice is yours, and if you are playing against Easier GPs in lower elos, then PTA/E-Cute will be the better choice to win lane easier.
I recommend Fleet overall against GP though because GP can sustain quite well with his corrupting pots in lane along with W, and he also has reliable poke that is a lock on ability with his Q.
If you run fleet, you can sustain his poke in lane.
Level 1 Gangplank has no pressure to out trade you, so use your vault aggessively.
If Gangplank ever Qs you, retaliate with Vault + many Auto Attacks to win the trade.
Since most GPs run corrupting pot, it's very important to keep tab on if he has the pots active.
To check if he has a corrupting pot active, click on Gangplank's character and on the top-left of the screen, it will show the corrupting pot timer under his name.
Do NOT trade with Gangplank while he has corrupting pots active because these consumables grant him more damage while active.
Your goal in the early laning phase is to get GP to consume all 3 corrupting pots as soon as possible, and every time he uses one pot, back off until it wears off before you go in for trades.
Level 3 onwards the lane gets really fun. The most important interaction is to practice dodging his barrel explosing with your E, Vault.
To do so, when Gangplank explodes a barrel, he will try to throw one in front of you to hit a Double/triple barrel combo.
The key to time this correctly is when Gangplank explodes his first barrel, immeditately retaliate with Vault, and if timed correctly, Quinn will dodge the explosions from the other barrels.
Master this mechanic and GP has no chance in lane.
If he misses his Barrels, immediately run him down and launch your whole combo on his to get a big trade win.
Ideally, you want to land your Q on Gangplank in lane first, and if you land it, go in for a quick trade becasue Gangplank cannot retaliate with his Q since it is a lock on ability, which means you will get a free trade in lane.
Even if you are behind in this lane guys, when you get 1-2 items, you will be able to 1v1 GP ALWAYS because your crit build will provide enough damage to destroy him.
All you need are 2 crit items and you will out DPS him in 1v1s.
GP is a bad 1v1 champ, and you can think of him as a poke AD caster mage.
He is quite squishy for the most part, which means our crit build will do wonders later on :)
Side Note: Gang plank can win level 1 if he plays it correctly.
The only GP player that I ever struggled with level 1 was Solarbacca, the best GP in the world, but most GP players wont do what he does.
If you see GP with ignite start, be careful of his level 1 cheese.
He will poke you 2 times with his Q, and then he'll flash forward to AA you, and this AA is his passive so he gets MS from it.
When you flash away, he'll ignite and then Q grasp you to kill you.
Overall, you hard win level 1, but if the GP plays like this, just be a little mindful of long trades early game.
Also, Solarbacca rushed bramble into me last time I vsed him, which was not fun lol.
If you see bramble GP, go Kraken rush and wait for 1-2 items.
You win 1v1 with 2 items no matter what.
