There's always an overabundance of jungle stock. Before midgame, I set myself the obligation to score 2 heralds, 2 dragons, gank 45 times and divert the enemys efforts to farm his own jungle. Before I head back, I have both west and east jungle of my own to errand and 2 more potential ganks in pushed lanes.

Not to mention defending deceased teammates' lanes and pushing lanes with the local where the enemy is mia.
