Shouldn't there be a hobbit in that group too? :p Well, maybe when ROM adds them.
Technically, both dwarves and elves can get out of their starting area via questing. Elves have to do so, I don't believe they have class trainers on Elven island to give them second class. They can't port out of Elven island till they take airship to Varanas (main city in game), and get second class then from trainer in Varanas.
Dwarves can port out of their area if they complete the instance there. However, nobody really does that. Dwarven city has the class trainers so easier to learn second class and transport out.
Once they are out, there is little reason for dwarves or elves to go back to their starting area, and people of different races can run together. And while they are locked to respective races (only elves can get to Elven Island, only dwarves can get to Yrvandis), there is a way to break that lock, by opening a portal to your friends so that they can get to starting area they don't belong in.

Oh, and people who have more than 3 classes are clinically insane.
