Haven't read it, but if it was the _only_ 'exclusive' that got put up on the store I'd be a little annoyed.
But if they all go up I wouldn't care, there are a few exclusives I'd buy with C-points, the mirror universe outfits come to mind...
I would love to play as a liberated Borg and would even pay good money for it, but it should be different than what the lifers got. If not I would be happy if they would allow them to be tradable on the exchange later down the road as a BO, it has been discussed lately. Or you can win them in special contest or PvE or PvP matches.
But I fear that if they don't make them offerable down the road, a lot of the people that got them as lifers, will slowly migrate to another game in a years time and there will be very few still playing. I know that in Star Trek lore there are few liberated Borg and we should respect that universe, but at least offer a few more special chances!!
