from all those games there was one game where you were significantly ahead of your teammates. and with stats like 1-11-7, 0-5-0, 0-9-5, 1-10-3 you wasnt playing well most of the time aswell.
you are right, this isnt bad luck but you needing to improve. if you are open for hints where to focus on:
- your farm needs to be improved, especially when you play something like teemo. teemo is a lane bully and if you dont farm well you cant bully the lane because you lack items to do so
- you die a lot in your losses compared to your kill participation which most likely tells me that you overextend or get catched off guard
- theres a reason pretty much everyone takes flash. youre open not to, but 2) may be a hint to why flash might work for you. it gives so much kill pressure, safety and reliability. and on morg its neccessary for the ultimate in teamfights.
- you are basically never carrying, even while winning, due to lack of gold and levels
when you learn how to 1) and 2) you will start to carry automatically because then you'll have the gold and xp to.
