From plat 5 to Silver 1 the new rank system

So i played all 10 games and won 4 and lost 6. I was plat 5 last season with 90 lp. I did alright my games that i lost, even though my score may not show. I was warding, clearing wards, map pressure, keeping my team up and helping them. All i did was try my hardest and got punished for it? Why are we getting penalized for doing good and team mates are the reason we are losing? This is ridiculous. My winning games i dominate and same things the whole game. Im going to have to play hundreds of games to get back to my SAME RANK. I'm pretty sure no one likes where they're placed in their provisionals. The games are set up so you have, or atleast i did, silver/gold players on your team and diamonds on the other. Resulting into an instant loss. I might quit as a result of this, just because riot never seems to pleasure the consumer. This game will be diminished in no time and i dont want to see that happen to the game i play every day. Riot please fix this.
