Well, I certainly won't find out Oasis's intentions unless they explain.

But... if I guess correctly, they intended to give 1 pack of 80 frags free? and didn't realized their blunder until...

People start 5 starring them in one shot, even had breakthrough reserves.

They took it off, but actually.. IMO the least Oasis can do is make 1 pack still available for those late comers.
