I was just playing a game where the first pick chose diana for me, and I chose nocturne to trade with them. We traded, I set my runes and masteries for ap mid, and took flash/ignite. I even chose the valkyrie skin. When the game starts up though, I see that I am still nocturne. So now diana is jungling with ad runes and I'm going mid against ryze with ap runes. As nocturne. It wouldn't be too big a deal except it was ranked, and we got clobbered early game. Not sure if anyone else has had this happen but it ruined my win streak I would love to have a screenshot for you but I'm not sure how you take a screenshot of such a thing.
