In ranked that has to be frustrating but I'm getting seriously demoralized with the amount of ranked people in leveling games. The experience alone those players have over us leveling is game breaking but then to toss in tier 3 runes and all the masteries and it's pretty much GG every time!
Would there be a way to disallow matching up those under level 20 with anyone over 20? At 20 you get tier 3 runes and 2 quints ... 20- 30 is a little more balanced (still not making up for the exp difference) but at least you can have a more balanced game. Us under lvl20 99.99% of the time have no runes due to not being able to use tier 3 under 30 and from the get go were vs players that no matter what will have stats much higher than us due to the runes and masteries.
