Played a Yi jungle, against a Yi jungle.
Other team invaded my blue, we warded it and Morg supp threw Qs in to harrass, while I invaded their blue/frog solo. Got it, went back to my red and when I worked through my jungle again to get down and gank bot lane, found that my blue buff was still alive.
I.. I didn't know what to think about that, but let Xerath get a blue buff 3 minutes in, he dominated ahri mid and I was left to gank bot/top all game.
Fed Cait and nasus kills until they were unstoppable, needless to say we won. But the failed invade just confused me so much!
