People don't cooperate though.
IMO, state of pugs has greatly improved. Ppl who don't cooperate either wipe or have to solo. While generally, you can blame it on your team mates that "they died and I have to solo" or that "we all died, not sure why, it always happens to me as I just need 20 more promotions and then I can solo", it still does not help. On PC, people do kick in game and very rapidly, I have seen it a few times already. Mostly, the experience is rather positive than negative.
Same thing happens in ME3. There is hundreds of bad-pug-complain-need-to-carry threads in ME3-MP forum. I've never encountered the extreme cases because when you don't consider your team mates just inferior decoys and instead try to cooperate with them, they do react in a surprisingly pleasant way. Carrying suddenly stops being soloing and becomes leading at least somewhat organized team to glorious victory. When you consider them inferior decoys, well, that is your problem then.
Of course, some ppl never listen and never learn. Although, this is a very tiny fraction and clearly a minority in my limited experience.
