No keysrone masteries. Low lvl game
still, why pair a lvl 10 against a diamond 5 :| smurf or not, u have lvl 1 runes and barely anythin in the mastery tree even at lvl 30, going unranked in any game assumes you're silver. not gold, not plat the only explanation would be that the diamond was playing with a friend, possibly helping the level 11 earn xp (or ip?) faster with the friend boost. The Golds are there prolly for first win of the day ip bonus, but I still don't see how theyre supposed to carry that. mhhhh no excuse
tha shaaaaame
EDIT: would be interesting to see the mmr total, as the OP cut that out. top has higher mmr, right?
