I have the same problem. Majority of my games have been against level 30's and I just think that is ridiculous. It makes the game unfair and unbalanced whey you have to go against someone with full runes and masteries. I have to say, this problem can be easily addressed, but it doesn't seem like Riot cares all too much about the low level community. Maybe in their minds, the level 30's are supposed to give us feedback after kicking our asses and calling us noobs. Yet every game I have been in, when facing against enemy level 30's, both teams become highly toxic. This problem is making it less enjoyable to play games. I'd like to suggest that Riot could cap the low level games by putting them in brackets. Say like 1 through 10, 10 through 20, something like that. As I am typing this, a friend of mine says that making brackets and capping the leveling would make it harder to get into the game, but I don't think it would. There are millions of players in League of Legends. Thousands play on servers each day. I'm sure that about 70% or 80% of those players are level 30, and the other 30% to 20% are low levels or smurf accounts. That is still a lot of players out of the whole League community. I would greatly appreciate any feedback on this matter.
