I have a few tips from someone who has done this themselves.
After Riot's alleged "soft reset" knocked me from silver 4 to bronze 5, I was able to climb back to silver in 120 games (now in silver 3 and climbing happily)
You are going about a few things wrong.
- You seem to be playing 1 champ, this is bad, play a variety of champs in a variety of roles, even supports
- If you win lane EVERY GAME, you need to start snowballing your advantage to other lanes and roam, roaming will get your teammates ahead and make the game easier to win
- You need to make calls if you're ahead, solo q has barely any shot calling, say, come on everyone let's take dragon, or rotate bot for the tower, or some direction
- PLAY SUPPORT, often people are forced into it and they're bad at it, a good support can really change the game
- WARD, place them, if you see the gank coming you can never be successfully camped "every game" like I've heard people say
- If you want to have a impact on all the lanes, pick a jungler who can gank early and often and take early dragons like Vi
- Group up, if you're ahead and AFK farming top lane and your team grouped mid gets ambushed and forced into a 4v5 fight, that is on them yes, but if YOU being fed were there you could have won the fight, so you have absolutely no right to flame at them
- Don't flame/argue in general, you will most likely never meet/see these "idiot feeders" again, so just work with these people for 45 minutes of your life to get the win, some LP and everyone is happy
- Please, please, please pleeeeeeeeeeeeease don't talk about ELO hell, not only does it bring on a negative attitude, but it doesn't exist, anyone can improve, and you have room for improvement too, never forget that.
- You are there for a REASON and do technically deserve to be there, not forever, but until you improve, you will eventually, mechanical skill alone doesn't make a good player, you seem like the kind of player that flames, you're attitude and team play are as important as mechanics
Those 10 tips should help you on your way, I wish you luck in solo q, you need it.
See you on the rift!
Bonus: Don't pick Shaco, he has no usefulness other than damage and brings no real cc and is useless in team fights, I know you can get alot of kills but don't pick him, just don't do it
Bonus Bonus: Don't pick high skillcap champs in Bronze ex: Kalista, Zed, Leblanc, Thresh Stick to easier strong champs that are better for solo q ex: heimerdinger, annie, kat
