Need an external observer/coach or something
Here's my situation, I can't carry out of Silver. I'm not doing bad or anything. I get good scores, usually ahead in gold, decent objective controls, show up to teamfights when inevitable but I just can't win. I know the only think I can control is myself but I don't know how I can improve further. I get ahead as a tank my carries don't deal damage, I get ahead as a carry an assassin or w/e ungodly unstoppable champion comes straight for me and I can't kite endlessly (think of Riven there, always a Riven...), I go support, get my carry fed but somehow we just can't win fights. I'm tired of coming home from work, logging on and expecting to climb if my performance is there but it never happens. I get that one win for that glimmer of hope then I'm slammed with impossible to carry situations.
Would anyone be so kind to help me?
