I have mixed feelings about race restrictions. On one hand, there is no real reason to limit race/class combos. Lore can be written to justify any combo ( hell, it's a sci-fantasy game). That said: I think it does make races more important if they are limited in some way. I wasn't going to play an Aurin, but now I will play an Aurin Esper at some point. I do agree that seeing a Chua Stalker would be cool, and I believe eventually the game will have more combos available.
