Oh, no... hehe. This is going to sound really nerdy, but I used to name all the PC's in our home network after different Tokyo metro stations (Kameido, Shibuya, Yushima and so on), and Ayase was the name of my own desktop PC. Some games have the habit of picking the PC's name as 'default nick' when you play multiplayer... and along that line it is.
I think you'll find depth in most classes. I couldn't really say that one class will require more skill than the other, as we're trying to balance them as good as we can. I suggest that you wait until the game goes retail or you got another chance to try the game for yourself (such as the Preview Events or other media events).
The name 'Ayase' comes from a subway station in Tokyo.
