Randomized picks should be fixed

Playing 3 times in a row the same champ in randomized picks gamemodes (Aram, ArUrf, customs...) shouldn't even be possible, but it's far too common. Players play those gamemodes most of time to get to play a wide range of DIFFERENT champions. When they get to be forced to burn their rerolls one or even two times just because they get a boring champ back-to-back to the precedent game, players don't even feel to dare trying once again to get a better champ for the next game. I possess about 60 champs, which is a pretty small amount compared to most players, but when I go playing full aram for a while, I always get the sensation to be playing the same 4 champs (5 if i'm Lucky as heck) without exchanging. Even on ArUrf, everyone got the sensation that there was Zed in every games, I even got him twice in 4 games played in a night. Even if he is OP in that gamemode, it's boring as heck playing the same champs in Something that is supposed to be random.

Rito should put a parameter making so that it's impossible to get the same champs from the last two randomized games you played, and by every additional games without playing a certain champ, the chances to get him would get higher. This would both fix the repetitive sensation of a supposedly "full random" gamemode that dosen't feel like to, and also give the occasion to have more chances to get a champ didn't got from some time ago, thus increasing the random aspect of the game.
