you try to help the lane that is doing the best imo
0/8 top 0/5 mid 0/2 bot help here probably
that said some games just are not really possible to turn around...
yeah. If a lane's too far gone, just abandon it, try to get another lane super fed, tell them to either turret hug, or if not even that's possible, roam and gank. force teamfights earlier usually throws them off. push as much as possible while you can. --- "That is why war is so tragic.
