My idea for a new Gangplank passive.
The main problem I see with
is that with the highest gold generation in the game he is meant to be strongest midgame, however he is gated by his barrel mechanic until lvl 13 while also falling off late game. The passive would help alleviate some of his late game woes including the fact that his ultimate does very little damage late game. The passive could be called "Plunder of the seas" (or something like that) and would give:
1 bonus AD, 2 bonus AP, and 3 bonus HP for every 40 gold in your inventory.
This passive would provide minimal benefit early-midgame (as purchasing items is more efficient) however late game would get him the edge he needs. I'm by no means an experienced player however I thought it would be a cool cohesive addition to his kit.
