it can't be not rigged, silver 5 is hell on league

hi, i got out of bronze like a month ago, im silver 5 at the moment im playing better than i never played rn and i still can't climb. Why? Because silver 5 mix boosted players, lucky players who should be bronze, trolls and afkers, smurfs and players with huge gaps of skills together. I've never seen a so hard rigging ever in all the fucking divisions of bronze, i've been in them all but silver 5 is a fucking hell. Rn i'm trapped in a hard pattern that i climb from 0 lp to around 40-60 lp and then i get uncarriable teams all the way until i'm back at 0 lp when i don't even played bad or changed my playstyle for a penny, and funnily enough i always get a win streak just after i got back to 0 lp, i don't even lose when i'm at 0 lp. what is impairing me the most also is winning +15 to +17 and losing -19 to -22, that's almost impossible to climb with these kinds of gains and im fucking mad at rito for making such an horrible ranked system meant to trap players at where riot think they belong.

P.S : i can so easily stomp my laners in silver 5 thats its disgusting that i can't climb even when i farm better than everyone in the game, trade enemies to hell and try macroing smartly.
