3 game win Streak to promos (free win woot) and then gives me Nami who I dont like vayne so goo luck suckas afk at lvl 7 and Im literally killing Irelia every time she gets to lane.
THEN Malz gets some beef and threatens to afk too and spends the rest of the match in chat telling the team not to report him while he is just standing at turrets doing nothing.
THIS is why I know Riot knows what kind of player each of us are and stacks games. Holds these babies for promos just to make sure you dont get it.
Riot does not just put you vs better enemy players, They but BAD players (not worse, BAD) on your team.
