Please do something about lower ranked skill gaps

This topic seriously has to be the primary one that irks me about ranked play more than anything. It's literally like practicing and rehearsing the mannerisms and tendencies of a truly mad person, cause only insane people would do the same thing over and over again expecting a change.

For literally the past FOUR ranked games in a row that I had, all losses have been due to one or two players feeding, the first of 4 being intentional after the Gnar had a bad experience in top lane. Why is it that I can do more than enough holding my own in bot lane, but in nearly every damn game, someone in top or mid lane can give 3-5 kills to the enemy before I can get 1-3? It hardly ever fails. I believe the problem is that skill in the lower elos is just way too ambiguous. The variance in skill between players in Bronze/Silver is just too damn high. It's crowded as hell down here, and time and time again I have to see myself lose because of a debacle I can only do so little to stop.

Can you guys at Riot please, for the love of gaming, do something about the variance in skill between lower elo players? You've already gone and made tier after tier for higher ranked players, yet us lower ranked players are stuck tossing Mario Party dice until we hit a 10 three times to finally climb. You know how depressing it is to go nearly 10:1 on support or 5:1 as an adc and STILL have to lose because someone just HAS to feed early? I can't even have some degree of faith that laning phase will go at least decently because of this crap. It's not fun. It's not constructive. It's FREAKING ANNOYING.
