Gangplank Ship Concept
On the bottom left corner of Summoners Rift theirs a body of water below a cliff. Imagine if when there was a Gangplank in the game his ship would appear down there. It could have an animation of firing cannons when GP ults, because in the tool tip it sais his ship fires the barrage. There could be custom ships based off your skin so there could be a ghost ship for Spooky Gangplank, a aircraft carrier for special forces and so on. I've been thinking about this ever since the new Summons Rift was released and i saw the water at the bottom of the map. Its something small but i think it would create a really cool effect for Gangplank players.

for a ship. It would be a super power couple until there was an opening and she shoots him. Plus it would be a way for him to get back a ship (as she destroyed his main one and when she took over Bilgewater.)
