Gear can now drop carrying up to three empty card slots. The roll happens once, when the item is created, and stays with that individual item forever.
Quest rewards roll far more generously than monster drops -- a quest chest is handed out once per character, a monster can be farmed all day.
Creatures were dropping a single gold coin where they should have been dropping a purse. Every registered monster has had its loot amounts and drop chances checked against the real tables and corrected.
Rotworms and trolls were the worst offenders, but almost nothing was left untouched.
The bidding system is gone. Stand in front of an empty house, say the word, and if you have premium and the gold in the bank it is yours.
Houses can now be handed to another player directly, with a tax, and every sale raises that house's price by 5%.
Premium time now gates the same things it gates on the global server: houses, founding a guild, the premium outfits, the larger friend list and your own private channels.
Your remaining time shows on the character selection screen and on your account page.
