Riot please. Why do you treat me so?

Last season I finished silver 1. during the preseason I got to mid gold 5 and am pushing up the ladder. The recent rank resets made me happy because it would give me a chance to go higher than I have before. I do good in my games. I go 7 and 3 overall. I'm thinking after the last game. GREAT I should get like gold 5 or 4 off this. ... Silver 3. not only did it place me below my preseason... which i can understand because it doesn't really count. but it also placed me below my end of season. GOING 7 and 3. sometimes I just don't understand this. So yeah. That's my complaint. Now to hop back into the game that just stabbed me in the back and try my ass off for gold again. QQ
