I'd like to reiterate that race is cosmetic are far as mechanics go. Certain slot skills are only available to certain races though, and choice of race depends on what you like to watch your toon do. Morphing Norns are kinda cool, but to me they look like they are running through syrup. Asurans have some cool slot skills, but other races have equal cool slot skills. And watching Asura run, dodge and jump is just plain fun. The character customization of Sylvari is like going to a salad bar and building a snowman, very fun. Charr can be an acquired taste, and some GW1 players just can't get over the fact that they are responsible for the Searing. They also smell like wet dogs. Humans are picked most often, just the whole identifying thing. Overall it is just individual taste. Classes are a whole other area. Anet tried hard to get rid of traditional methods of looking at classes, and did a pretty fair job of it. To the extent you can take pretty much any mix of classes and run them through events and dungeons. Each person likes different classes, and there is no "right" class. Some do take more thought on working them to the max, but can still be used effectivley by those with basic, "roll yer face on the keyboard" skills like me. And Raven is right, a flame throwing, grenade tossing little squirt of an Asura has a lot of amusement value.
