RITO Your system managing doesnt work !!!

I'd go and play some games when I have free time. What I noticed is it no sense what so ever ..your game doesnt even care if it will place me vs diamond,gold or platinum. Like today I went to play aram and some normal games. I am unranked because I play only normals. So my teams were silvers the enemy team - 3 gold 1 platinum and 1 diamond. This doesnt make sense to me fix your stupid system because it cannot place teams like it suppost to we lost visiously the game because we are low players vs players that play better and got better expirience in the game from us. How is this suppost to be a fun game if the game cant even pick teams that are equal?
