I've seen a ton of discussion on these boards about quitting/ragequitting/etc and think it would be cool to get some discussion going on about it.
There are many different scenarios which might warrant quitting. Teammates leaving, teammates feeding, or just being outmatched by the other team.
For example, the other day I did a 2v2. My partner was Oak, I was regulus. My teammate was probably very new to the game, because he would basically run up to the enemies (usually both of them, him by himself) and just start meleeing and using occasional abilities at random. I would try to get over to him to help out, but usually by the time I got there the damage was done. He would stay and fight until he died (not even attempting to run). I tried giving him tips in chat, but he never responded or changed the way he played based on the advice I tried to give. After about 5 kills on him, them being several levels higher than me because of this, I decided to quit. I'm sorry, but I had better things to do with the next 40 minutes of my life than sit and get trounced by my thoroughly fed opponents. I appologized to the other team and told them I would be leaving (Of course to be mocked by the usual "OMG BADDIE RAGEQUITTER"), and then left.
At the same time, I don't think quitting is OK every time you're a little down. I've seen a lot of games where players have used unique strategies (citadel purchases, defensive play, creep farming, etc) to come back and win. The only times where it seems like a victory is not possible is either when you're stuck with an AI player, or you're stuck with an opponent who continuously feeds (the two are really the same thing...) If you're playing a 5v5 it might be possible to try to compensate, but in a 2v2 or 3v3 it's pretty much impossible.
So what do the players think? Is it okay to quit a game that's obviously a terrible match? For me, I honestly don't think it's that horrible if the other team quit if the match is extremely unbalanced. For me the most fun games are the ones that are neck and neck the whole time, and the outcome isn't decided in the first 5 minutes.
Your thoughts?
