In watching the recent game economy it's become apparent that inflation is a big problem. In lamens terms, CE is crazy expensive and it's only getting worse. I only think it's fair to initiate a cap that prevents individuals from selling CE above a certain price. Otherwise we may soon end up having an issue with donating players setting ridiculously high trade prices simply to get rich quick off of players who can't donate. And BTW, just for all who read this, I donate myself.
Been discussed to death in other threads. Quick breakdown of more realistic (and less intrusive) solutions:
1) Vendor that sells Mist Energy Tanks at a fixed price (4-5k most likely), possibly limited to one in inventory at a time.
2) Initiate a listing fee for energy buying/selling to discourage "walls" that artificially inflate the market.
Along with the above ideas, the game sorely needs a crown sink for end-game players that have nothing else to do with their energy and don't need crowns for anything.
