I didn’t think of this really until seeing this Halloween event and it hit me. I also didn’t realize this because it’s rarely done having a card as a top reward.
That’s great…for people that don’t have the card. For those of us that do? It’s just runes and no matter how much runes it converts to that’s not a top prize at all. What I suggest is put something in where the game recognizes if a player has the reward card or not. If they do then when they are about to receive said card give them a random card in the same category instead. If you were going to get a rare then instead of that specific rare get a random one instead. Heck, could even be from the same set and if the person has all the rares or Mythics or whatever then awesome for them and they still get a dupe. But just to have a single card that the person already knows he has? No incentive really to try for those points. Or a pack instead. Anything but a single that the person already has.
