So yeah i need help.
So the last couples of games where a complete disaster. I tried seeing why I lost those games and surprisingly most of them were not my fault. Actually I did a lot of mistakes but the most crucial mistakes happened at other lanes . Hell I tried to help them but we couldn't .Take for example my last game Draven has taken a big lead and even though I tried to help bot to shutdown Draven we failed .Getting even more ahead of us. Yasuo kept pushing thus getting himself constantly ganked. And then he started blaming while I was busying trying to help bot. Should I had tried to get him fed? Certainly but as I said earlier that was not an option since he pushed all the time. Winning was impossible because kalista just couldn't stop getting hooked by blitzcrank. And lee continued to buy hp against a fed draven. With botrk.
So I ask now as a low elo player what am I supposed to do when other lanes are doing horrible and just don't know how to play safe. And yes I try to help them . But when I'm at a disadvantage (for example when I'm against kata) roaming to help them is not an option since she will have the lead. Even if I was on the same ground she can simple follow me. So roaming is not that reliable. Encouraging is again out of the option because it takes a lot of time. The worst part is that this happens quite often lately. Like another example (actually this is worse). The second last game we had an twisted fate jungle. It looked like he trolled but I cant say for sure (he was angry because they picked his yi). I was against katarina helping bot was out of the question since I wouldn't deal dmg to them because I have fallen behind . Twisted fate was busy recovering his lost cs because he died to the 1st red. Reaching late was out of the table because we couldn't really stop both yi and katarina from ripping us apart because we had twisted fate and pantheon. And they had riven, and ashe. And thresh.
So tl;dr how can I climb division when another lane has fallen way behind and I can't help them.
