I think that you should be able to choose the merc you get your ranked cards for. If you are like me you just want to get a ranked card for your favorite merc so you can have a unique card that not many other people may have. Its a real kick in the balls when you grind out to get enough points to buy a ranked case and then you get a card for a merc you dont even own (Thanks). I know there will be people saying "If they do this then people will just play ranked enough to buy a case then stop playing". To be fair you do have a point but in saying that you arent guaranteed the card you want for the merc so you might have to play more to try again.
