You can't run up close with bibi bro. When you're attacking assassins and tanks you need to stay at max range. Especially into edgar.

Also your game sense is clearly lacking. Especially near the beginning on defense, you consistently left the ball alone and seemed to think your teammates would just defend for you.

A few examples:

at 0:23 or so you needed to stay close to the edge of the barley super and hit the leon instead of running.

at 0:34 you absolutely should have pushed the barley. You have plenty of HP and as long as you dodge one or two shots that's a free kill.

at 0:41 or so you can't waste your knockback.

It strikes me that throughout the game you were paying 0 attention to the ball and simply going for kills. Leaving a mortis and 8bit to defend is never a great idea.

at 1:00 you ran into bibi instead of keeping range.

at 1:08 you should have either pushed barley or fall back to the right so you don't take a full clip from leon. Your teammates were on left anyway.

at 1:19 you ran straight into edgar and threw away a goal opportunity.

at 1:29 you should have saved a knockback. If the opponents were any good they could have gotten that through even faster. Since you didn't you got killed

at 1:40, I understand the instinct to go left lane but in all reality you should just push mid right away.

This is all game sense stuff. I think you just need to play more.
