Bronze feed.

Having issues with climbing because I cant carry every game, no matter how well I'm doing.

Check my match history before flaming me, I don't do poorly, I VERY rarely lose lane, I usually win if my team can collapse onto objectives with me, or if there's a pair of players sticking together, I can reach with them and 3 man objectives. But most often, the bronze in them takes over and they split up as soon as I join them.

How do I get out of bronze if my main issues at this point honestly do lay with other players ?

I'm not saying I have no blame, I could be a god and carry every game, but really, this is a question about team work. I have been actively working on my ability as a player and will continue to do so (evidence in match history). But for the love of all things good what do I do with a bronze team if it gets to late game ?

Am I honestly expected to babysit the entire game to climb the ladder ? As soon as one good thing happens, the whole team scatters like ants, how do i counter act this ? How do I keep people focused, and help them realize that one good team fight doesn't mean you're invincible and free to roam the whole map by yourself ?
