I only found out about NS2 being available for beta purchase after the offer on black armor ended. Very disappointed.
Personally I think anyone who buys the game before it's even finished deserves the black armor.
But so as not to offend those who wanted to be even more extra special for having bought it during an earlier point of the beta, why don't we give their version of black armor a special armpatch of some sort. That way they can still say look, I'm even more special, without denying others their justly deserved paid beta participation armor.
