So que the angry folks who paid for this and don't like others getting free stuff. For the rest of you enjoy something free from cryptic.
It's not that I'm mad that other people get something for free, it's that I don't get something for free. Yeah, it's just unlucky that I bought 4 costumes and that was one of them and there's nothing I can do about it.
It would have been more fair if they would allow you to choose any 1 costume for free. Basically give a costume requisition. Just like ship requistions or STF requisition. At least that way, they'd avoid people complaining.
I'm surprised that's not how the cstore is set up. Instead of buying a costume pack, just buy a costume requisition. Then while in-game, you can redeem for the costume pack.
