Plenty of other games have flavor text on their generic cards. And the name doesn't have to be as boring as "Niten Warrior"; that was just an example of something generic sounding. Perhaps that wasn't clear. Are flavor texts on generic cards somehow worse? *All* the cards in A:N are generic, and they've got great flavor text IMO. Not a suitable tone for L5R mind you, but clever and fitting to the game.
@Crawd could you point me to the previous debate?
