Heh, I really dunno if this argument is applicable really, everyone that plays league of legends is prone to having good games, and bad games. You can carry a game very well, and than again not get a kill the next game. It is all teamwork based, sure lane phase ya'll have your lanes and you fight it out until a tower goes down with ganks and such, but once the team fighting starts, all bets are off. Its all in the teamwork of how you position, and act in the fight according to your teammates. Thus communication and focus is key. A lot of games, I've been in or see, one wrong move on who is focused in team fights can change the games out come. Sure you can get the trolls occasionally, yet no one will ever be 100% perfect at this game. Not saying you can't be great at the game but, we're all human, and making mistakes is in our nature. Best bet is to find a team that you can click with and have good team work and work your way up the ranks, maybe slow but you have to keep in mind you can't win every game. Sure everyone wants too but hey, its a game to have fun with as well.
