Yet another discussion about ranked placement

I know this topic is beaten, but the more we write about it, the more the chances Riot will react.

I ended the season in silver 1, then didn't really pay attention to games and finished the pre-season in silver 5. Please bear in mind that I finished season 4 silver 4-5 as well, and then went 6-4 in my series and was placed in silver 5. This year, however, I tried my best to get to silver 1 or something, and ended up in... BRONZE 3. I understand that I'm not the best player over there, but anyways here is my placement games stats:

1. WIN. - 15/7/13, carried, most gold, damage to champs and total damage in the match
2. WIN. - 8/5/14, carried, most gold and total damage in the match
3. LOSS. - 8/8/9, most gold and damage on team
4. WIN. - 3/4/4, not my best Jayce game
5. WIN. - 9/6/4, average performance
6. WIN. - 19/5/8, carried by me and our top laner Darius. I got most gold, damage to champs, and total damage in the match
7. WIN. - 6/9/9, the enemy had too much cc, but i still got most gold, most damage to champs and total damage on team. We also won because of my baron call and then all mid call.
8. WIN. - 14/10/15, carried, most gold, damage to champs and total damage on team.
9. WIN. - 7/5/8, carried, most gold and total damage in the match
10. WIN. - 5/7/8, almost threw the game because my team wasn't listening to me, but ended up winning because we made peace :)

So, Rito please, fix this. Thank you!

Best Regards, Nuaran
