The biggest problem that has ever occured to LoL is smurfing.
I have never ever played a game where there are 2-4 smurfs on each team, every match. Us noobs will not improve when we get stomped on, it makes my experience of the game really bad. Smurfs are like a barrier that pushes out new players. What usually happens is that one or two smurfs on the opposing team gets really super fed and then it's game over. Either that or all the smurfs on both teams plays evenly while us noobs gets to just spectate them fight. This really ruins games, and LoL would probably be about 20% more popular if it wasn't for smurfing, because LoL is a really really fun game but meeting players who has years of experience and knows every ability, passive, counter and matchup for every champ in the game will greatly ruin the games for new players. Noobs will either go with 10-20 deaths against a smurf or they will maybe have less than 10 deaths if your teams smurf is better than other teams smurf. All I want is players to stick to their mains, I would rather want noobs with macros than smurfs. You would probably say that you learn more from playing with better players, well it comes to a point wherethere is absolutley no way what so ever that you are going to to learn anything cause you are just being stomped on so extremly hard. I just wish for a more noobfriendly game, that everyone can enjoy, and with all these smurfs, most new players will leave LoL, cause there is no fun in not getting any kills or having any impact on the game.
Thanks for reading this and I hope that you think before you go on your smurfs and bully us new players just to make yourself feel good, cause it is really unfair.
