I would advise going for some class that can solo well as first choice.
I started out on red as a monk and while it was fun, you're probably better off with a more independent class to start with since you'll be soloing quite a bit.
P.S. Just ask for groups in OOC or join Sanctuary guild. It's amazing how easy it is to form a group when you ask, even with as little as 15 players online off peak. Mostly because everyone has several characters in various level ranges due to fast exp.
So if you're proactive you can easily start groups , is my experience.
