Problem with smurfing...
Their have been multiple games where we are winning early on, but as soon as late game arrives... A team fight errupts and what looks like a victory is soon to be only a glimpse of what could have been. The diamond or whatever smurf player arrives being completely superior in mechanics and skill and just takes out everyone by themselves.
I am sure it's fun smurfing at all, but it just straight out ruins the games for other people. So please stop doing it...
