Elo Hell? No hate please.

Well last season I got S4. I gave up after 10 straight games with an afk'er on my team (i was at s3 from s5). I was moving up really quick but the continuous trolls and afk's just made it more frustrating because in ranked winning matters. I never feed. Lately I've been playing akali to help me carry out of B1 (even though i won 7/10 of placements but whatever). I will win my lane and roam like no tomorrow. So bot lane is feeding so I go help them out 90% of the time it;s a successful roam. I or my adc get a double kill. But...the feeding still continues. So by now I'm living in top or bot lane pretty much and I'm fed. But when you have 1 fed assassin vs 2 fed players (usually their jungler or adc) I can't do a 5v1. I try to encourage my teammates to stay positive and give them help full instructions on positioning and who to focus etc. etc. So here comes team fights. I do my job I one shot adc and try to get their apc. But by then my whole team was just nuked and I'm alone running for my life to safety. I'm not trying to be a whiny bitch but I feel like even helping out my teammates and giving them kills does nothing. I mean i dont know what to do guys. I mean I want to continue ranked so I can move up and better myself as a player but matching me with utter retards gets me no where. I get it most bronzies are bad. Pretty much I just have to hope the other lanes are dumber than my teams lanes. If roaming and giving them kills to get ahead does nothing wtf am I supposed to do. No one wants to listen for instructions and walk into 3v1's like nothing. But they don't listen. I know I'm not Diamond worthy or anything like that but I just need advice though. I get into promos for s5 won 2 in a row and smashing like hell. But then my luck gets me with people who have never played a certain role, feed, troll, afk. If only I had a chance to play with higher ranked people to show I'm not so terrible I may have a chance but it can't. So GG rito or nah?
