Economy
The current item drop system doesn't function well as a reward mechanism. It drops many items on players who aren't interested in them (the items are extremely common, or they're for a hero the player doesn't play), and in the process dilutes the value of the items. We'd like to get to a place where dramatically fewer uninteresting items enter the economy. We don't have a complete solution yet, so we're going to move forward step by step, taking feedback from you as we go.

Drop list now includes full sets, treasures, bundles and items at a rare rate instead of frequently dropping common items Players with an active battle booster will receive a free Treasure of the Rotted Gallows. Players who had an unused purchased battle booster in their armory will receive a free Treasure Redemption Token.
 * Item drops are now entirely time based instead of level based.
 * Battle boosters have been removed from the game entirely (we actually removed them from the store in September).

Treasure Redemption Tokens and other items that can be redeemed for treasures can select this new treasure. International 2013 Treasure Keys may now be redeemed for treasures. The items in this treasure can be traded/marketed in 3 months (February 1, 2015). The rare rewards from this treasure are not subject to the trade or marketing restriction.
 * A new treasure, the Treasure of the Rotted Gallows has been added to the game.

Bug fixes

 * Fixed custom chains not appearing on both sides.
 * Fixed Greevils not having their particle effects.
 * Fixed alternate hero icons not showing consistently in the UI
 * Buyback button now only accepts left clicks.
