yea you outdamaged your adc as support , yet you were still 4th dmg on your team , you were also :
- highest deaths (!)
- lowest wards placed ( do you know what support does ???? )
- you placed 1 pink ward ( do you know what support does )
- you did not sweep any vision ( do you know what support does )
- enemy support did 15k dmg more
look for problems in your plays , you deffo lost this game for your team , they were trying to hard carry you and you did not help much and you were not supporting your team by doing what supports do. If you continue this trend of looking for mistakes in your teammates not yourself you will never improve fast.
Also this happens freequently and yea , you are not experienced player so you may have some lack of game knowledge but stop blaming others with this 0-15 bullshit because i can point multiple games where you went 1-9 1-6 1-9 again and you did dmg lower than your support. You are matched with lvl 30 and bronze guys that play the game for way longer nobody expects you to be good but you seem like the guy who blames his team while he sucks himself
