Unskilled players on ranked?
So i recently started playing ranked and everytime there are feeders in my team, im not the type of guy who blame his team for losing but when i am going 7/0 and got two towers down and then i look at our bot and adc i find their score 0/13 and the enemy about to get into our base its not my fault. is there something that im missing here? i mean i try to help my team and not just stick to my lane but sometimes it impossible they just die over and over again nonstop and you can tell theyre not trolling, im b2 btw got demoted today to b3 because of this. does this happen to anyone else? or is it just cause im bronze? is there this kind of thing in silver?
