So let me see if I have this straight--and, while we're at it, explain things to people not in the beta. You get items from battles or starter packs, and all items can be sold for gold (particularly Treasures, though I could see myself keeping around a barrel and some bacon in perpetuity). It LOOKS like gold price for an item is based on rarity, not on level. A Common item gets you 1 gold; Uncommon, 2; Rare, 5; and apparently Epic, 20, though I haven't seen it and I don't know what other rarities I may be missing. "Sort by rarity" is therefore identical to "sort by cost." Is this intended? I imagine it won't last into the release version, else those buttons are redundant. But if it IS intended, then it means that gold is on a very interesting economy. As you go up in level, you need to earn the same amount of stuff to buy your new equipment. Further, using pizza to get a pack and then selling it is only moderately useful, but equally useful no matter your level. A single gold coin has a relatively high buying power. Amusingly, I can imagine people having more pizza than gold lying around. Edit: Also, currently, Raid on Ommlet is a quick way to make 7 gold every day since the loot is static. Not much, but it's money for very little effort.
