It still seems like a bad idea to me. They should leave the old adventures and card packs up for sale, just put them under a separate tab in the market. Put everything available in Standard on one tab and everything else in a separate tab and clearly label them as "Wild only" so that people don't accidentally buy cards that they can't use. Then people won't be locked out of the single player content and collectors can go for a complete set of all cards by buying the packs that they need the most. It seems like Blizzard is willing to completely cut their old content in order to keep the client as simple as possible, but this is ass backwards to me. The game shouldn't be constrained by the client's old UI, the client's UI should evolve along with the game.
UI evolving?
