Not for the really popular packs, since I think those packs are a big source of revenue for Kingsisle. I could see a few of the older, less purchased packs being allowed to be bought for Gold though.
Yeah, it would probably have to be a higher price, though that's fine (though I don't remember what the gold cap is for lower levels). We definitely need something or some things we can regularly spend large amounts of gold on; I'm tired of always being at max.
