If you are 0/10/0 and no one on your team is ahead or even its time to give up. Especially right now. I'm not saying "Fuck this leave the game/afk/feed" but just surrender if you can or try until you can. If you can't turn it by 20 minutes the game is over. I was 0/3/0 with poppy top vs swain. Jungler ganked 1 time and it got me enough gold to snowball. But the only reason we won this game was because my bot lane was also ahead. If they weren't, Swain would have carried the game.
One game I had my bot lane go 0/17/0 combined. That is a game you give up. I am all for never surrender when you have a chance. But its another thing to be like "It's 0/50 never surrender you always have a chance!!!"
