A good question to ask also would be about how the classes are in Velious. Classes not as vital on raids now, later become quite useful.
Ultimately, it's the same thing I tell everyone.. Pick a class and race that you want to play and will have fun playing. You can form groups on your own. IF your big concern is end game stuff, research the classes and see what they do on raids. If you are more focused on the climb up the level ladder, pick a class that you will have fun playing in the various zones while leveling. Find a good guild and have fun with the members of that guild. It's not a guarantee of always getting a group etc. but it does help a lot.
