I'm all for the drop rates being adjusted or the card value being increased. I got two Shivas in a row from two tournament reward platinum packs, which meant I essentially got a Shiva and 200 MGP which isn't enough for anything given that a bronze pack costs 2.5 times that. A platinum rarity card should at least be worth the price of a bronze pack card. It's even worse for some of the other cards that are rare drops from early dungeons. And there's nothing worse than getting a bronze card as a drop from something, because they're not even worth the trip over to the card counter to sell.....

I'm personally fond of the OP's edited in idea of an actual exchange counter where we can trade in a few old cards we don't need for a card we actually want, with the amount we need based on the rarity of the cards we trade in.....
