I'm on a light server, and yeah it can be a real pain to find a group most of the time because there's no more the maybe 10 people if that on the planet that I want on. I now started a small family type guild just to notice that still no one wants to party unless they get stuck on their story line. I see nothing wrong with it, but as it is a MMO I do tend to think that there should be a lot of parties going on.
I also see there's to many people that have/had played WoW. So we tend to get a lot of people saying I don't want to party with a pug group ,or saying I don't play with people I don't know. Did this game not just come out how do you expect to know everyone if you don't even party. I had my trouble of groups, that's why if I make a group and lead. If they don't listen I call them out. If they still mess up I kick them and get someone else. Anyway it takes time, but you'll find people that are wroth grouping with if you really take the time.
