So the pirate needs some love. His jungle is too slow. He's outclassed in the top lane.
He has the makings of a really fun support, especially with the pickpocket mastery. Therefore, instead of making his "e" scale in power with levels, why not give it a flat boost and then at level 1 it applies to GP, level 2 it applies to GP and the nearest teammate upon cast all the way to level 5 where it would apply to all five teammates. This would make his "e" a viable support skill at level 2.
Just a thought. Because I want to play the pirate more.
