jungler players, ganking lanes can do more than net kills...

you're job isn't to find lanes to get kills in. leave that to roaming mids. you're job is to get lanes all big and scary and last hit drag and baron, not have the most kills by the endgame

(mind you some junglers like Yi are in it for the kills, and getting kills isn't always a bad thing. problem is my scrub rank, and sometimes me :p, doesn't know what to do with kills come late game)
