Gangplank is a very key carry in 3v3 and this build will carry your team to victory 24/7. gangplank is all burst damage so stay completely away from laning at all. also his ult is horrible if i could i wouldn't even level it up. Also since gangplank is easily killed because he is the squishiest champ in the game you really shouldn't touch a lane all game, so stick to jungling and don't even think about helping your team.

Most of gangplanks abilities are horrible so his q is going to be your main attack, if you could don't even out leveling points into them just his q.

Ranked is going to really test your skills! when playing ranked instead of your 6th berserkers greaves i would get a dorans ring, you need that AP to really melt health.

Runes are over rated and when i made this build i had just played a teemo. **** teemo.
Enjoy the build have fun ganging some planks.
