Can't rank up
hi everyone, i have a question for you all. I am currently silver 5 (demoted from silver 4). I have tried playing almost every role and doing well. Each game i go positive kda (ex. 4/2/5) with no feed but my teammates is 0/7 and 2/10. I roam a lot and help teammates get kills for them to get ahead. The problem is that the second i leave they die. As i'm roaming i need to have an eye on for example my enemy midlaner and my turret. If i leave for to long my enemy goes and roam aswell or takes out my turret. My teammates keep going in 2v4 even if they are behind with 7 kills.
What should i do because i have like a 10 losing streak?
