Well i dont know what more can be said on the matter.
Rage quitting sucks, had a god match with a premade earlier and it got ruined because a guy quit after 2 mins. He didnt die just quit. I dont know why he left, ruined the game for me, but i wont go so far as to say he was selfish or intolerable person. Maybe he had something to do, maybe the game just put him in a piss poor mood and he felt like he had to get off before he broke his hand on his desk, or heaven forbid send a flying knee through his monitor...
I've played with Raining before, cant remember if it was on or against him but he seemed like a decent player and trust me, if someone on your team dies 2 or three times early on it leads to alot more deaths/death situations for the more experienced players on your team. Its a shame he would handle the situation in the manner he did. I've had a rook die 18 times one match, he apologized again and again and you know what at the point i know im boned so i told him we all have off days and for some reason it made him feel better, i'm sorry you didnt have the same reinforcement.
Welp........... i guess just try to avoid players you know are jackasses and try to play as much with good folks. I've played with a variety of folks and i have a good idea who i will avoid and vice versa.
Anyways welcome to the community.
