Season 6 Placement BS

Riot you have fucked up season 6 so hard. I feel like quitting this game. Ended the season Gold V, won 6, got placed Silver IV with and mmr of 1368. I dont mind my placement, but my friend was Gold V last season won 6, with an mmr of 1289 and was placed Silver II, TWO DIVISIONS HIGHER!. Whats more my other friend ended Plat V won 7 games, and was placed Silver III. Riot fix your shit, this ranking system makes no sense. It is complete RNG isnt it? Another mate of mine was placed Silver III after winning 4 from Gold V. I am done with this BS season, you've lost alot of respect from me, and im sure the community. This is not fun, this is not a mild reset, this is plain bullshit, fix it now. You've lost a player.
