I think it is pretty cool overall, however I've had mixed experiences with it so far
Trade chat pug - roleplaying server, people were extremely nice and polite and discussed tactics with others, however......execution was horrendous, dps and hps as well, it is like they pressed random buttons or just did nothing most of the time.
Guild alt run - am a casual in a raiding guild so some of the raiders took their alts. Was okish, cleared it but with some issues because people sometimes are pretty bad at their alts, mostly because they try a completely different role. Tank playing a tank alt will always do better than a dps playing a healer alt for example
Oqueue addon pug - was...weird. We killed stuff after some wipes but no one spoke, ever. No one kicked the ungemmed unechanted bad geared ones or afkers either. I didn't leave because I was on my dps alt so finding a group is hard enough.... That not speaking part was really weird, like playing with robots. No responses to questions or whispers or anything >.<
