On the collectibles issue: I have to comment that the game desperately needs a good bottomless Platinum sink. What if there was a vendor that sold eberron dragonshards (small/medium/large) at very high prices? I'm thinking something like 250K (small) 500K (medium) 750K(large). Said shards can be turned in for various goodies (already, like 20% xp pots), or used in crafting (with the new system). Having them available via a vendor would actually stimulate the AH, since undercutting the price of the vendor wouldn't be that hard, and it would suck massive amounts of platinum out of the system on an ongoing basis, making it actually valuable to a lot more people. You can also add some collectibles to the mysterious remnant dealer.
