Ranked series and MMR is extra broken.

So people complain about this time and time again. Elo hell is real though. So mmr has been around since the beginning of time i guess. I finished s5 in silver 4, i also have 3k + games played so i cant help but be experienced and serious, but not once have i been matched with anyone with my number of wins. So i finished season 5 in s4, and i finally decided to do my ranked series for my 10 game trial yesterday. I worked my butt off everygame leading in cs, dmg, dmg vs champs was already highest or tied, objectives were always priority, contributing to team was also priority. Within the 10 games i won my first 9, but noticed i was placed vs bronze while i was unranked. On my last game, i had a duo that went bot and asked the team to trust them as lee rengar bot where i felt i would have to balance by picking adc range jg. Everything was fine till bot started feeding. The problem was not in that game but in the fact that i went 9-1 in series with highest ingame stats and all objectives prioritized and i got placed in BRONZE 4. Not once in 5.2 was i ever bronze 4. League,riot, im disappointed that you can cripple experienced players because of mmr when you put a shackle and chain on experience. People who take the game for granted and lower your mmr because its based on wins is not a fair way to deal with your players. Games played should also matter and causing experienced players to suffer for balancing purposes is not an alternative. This rank system is throwing a whole bunch of cats in a pool of water to drown rewarding those who survive, knowing cats wouldnt touch the water to begin with.
