It seems like I have a disproportional number of feeders on my team who always blame everyone else and then leave. Life sucks some times.
I just had a horrid TF on my team that kept ulting right by turrets and dying. He left, we actually did better without him and ended up winning. Anyways, after the game it showed the nice big red word LEAVER under his name, but he still got the win. Great lesson for him.
I didn't report him because I looked at his profile and felt pity for him, his last matches are just awful. I hate reporting someone just for being bad. At least he tried.
