Quitters defiitely suck. You just need to try and find a tight nit group of people to play that don't quit. Find a nice little online gaming community of people you enjoy playing and stick with them. That's the best way to get enjoyment out of online gaming. If you continue to play random people all the time expect to get burned about 75 percent of it.
I've met a few great people through playing random games online, but for the most part I've met a bunch of idiots.
