Gangplank is such a strong jungler right now
In season 5 jungle it is hugely beneficial to have healing/sustain abilities, as you only get 2 health potions at level 1. Gangplank gets free healing from his W, which is unusual for a jungler to have (apart from Warwick and Fiddlesticks). Gangplank also gets a bunch of free damage from his passive and AD steroid which allows him to clear the jungle at a competitive rate.
Gangplank can also gank relatively well, thanks to his ranged attack. Although it only applies 7% slow effect, it is better than nothing. After level 6 Gangplank can help his team and pick up kills/assists anywhere on the map, and if he is nearby, he cans slow his enemies in a massive aoe and catch up with them.
Gangplank is a melee fighter and he's really good at dealing damage upfront, but because of his kits Gangplank can also deal significant damage from a safe distance with Q and R; this is hugely important because it allows Gangplank to delay buying defensive items mid game and stay alive at the same time.
What do you guys think?
