What's missing is not people who wants to group it is people forming group. I'm always surprised 3 months after expension release how many people still don't know how to run a zone they have been in 20+ times in. That's a fact, too many great players got frustrated of carying lazy ones so they are not motivated to start group anymore, it is not kindergarden! Even if I have all I can get from Heroics, I still enjoy running them and I'm sure there are many like me. If your guild aint active, find one that suits you.
usually it's the tank who has to know the strat .. dps just burn mobs .. or assist but yeah me too .. I fear sometimes starting a group because (especially on my alts who need grouping more than my main) I don't legitimate to do groups. I don't feel my bruiser is good enough or I fear my warden wouldn't be able to keep group alive. but at one point .. especially when I play the bruiser .. I force myself now to start creating groups otherwise I won't ever get better gear :/
see lots of people asking about PQ being up, but not really any pugs for dungions... been needing last heroic run for epic for about 1 1/2 weeks now trying every day for a group and no luck...
