Fine if you rage at me, but at least still contribute to the game.

As a support main, I don't play adc much. Today I played a blind queue (I know, my first mistake) and got stuck with adc role. Picked Ashe to play, I have a leona support, so I figure this should be nice, she could engage on the enemy and peel for me, etc etc. At the beginning of the game, I explained that I don't play adc much, and apologized for any mistake I may make during the game.

Enemy has a trundle support and Ashe adc, which I thought was okay. Everything starts off fine in our lane, mid and top aren't doing well, but whatever. We push to tower, and I decided to try and catch up on my cs, (I was down around 20), which she gets rather angry about. This whole time, she had been engaging every one of our fights on trundle and got mad when I attacked the enemy Ashe over Trundle and called me useless for not being able to kill the trundle. Soon she begins to leave me during fights, even when we could win it, she would just turn around and go. She would spam ping at me, doing it more often after I politely told her to stop. By politely, I mean "Please stop spamming ping, it is very distracting."

Fine if you rage at me, I know perfectly well that I'm not a good adc. But still, this sort of behavior only sets me behind. Call me whatever you like, but if there's a half health kog that we could kill if you just keep him stunned long enough, don't walk away and lose us the fight and the game just because you are angry I'm not doing as you expected to.

tldr Just because you are mad at your teammate doesn't mean you should just abandon them and fuck up teamfights just for spite.
