Choosing a new PvE server
Try guesting on Tarnished Coast for a while, and see if it suits you. I do nearly all of my runs with guildmates, but I usually see a number of people asking around for groups. I always see people around, and its a mature, friendly community (barring map chat at times).
Also consider using http://gw2lfg.com/ for dungeon groups.

New Player Outreach Thread
Tarnished Coast has a very active and vibrant PvE community. There’s often people shouting for dungeon groups in LA and the dungeon maps, and most of the Orr Temples are open most of the time during peak hours. I’m in the process of leveling a few more characters and there is no shortage of other players in the low-level and mid-level areas. In general, the community is also very friendly and helpful – people will stop and rev you, shout when a rare DE is up, and keep most conversations civil.
Before you transfer to any other server, since you are mainly interested in PvE, I would suggest that you try guesting for a few days to see if it’s the right server for you – but if you do decide to guest to/move to TC, don’t hesitate to give me a shout!
And as Falunel mentioned, gw2lfg.com is a great resource for finding a dungeon group.
I’d definitely guest on a server for a day or two before making the move. I’ve been on Crystal Desert since launch, and I love the community. I’m also largely a PvE player, but I do a bit of WvWvW. There are always friendly and helpful people in the zones, especially in the lower level and Orr zones. The dragon fights always have lots of people, as well.
