The Heavenly Domain had a huge world and thus had many cities. The experience loss and equipment drop chance was higher here than in the normal servers as well. The official statement was that it was done to increase interactions between players, but in reality, it was to increase competitiveness. In Glory, equipment could be bound. However, from a monetary perspective, binding the item wasn't good. If the item was bound and one wanted to switch equipment, the player wouldn't be able to sell his old equipment for money.
This made binding equipment a difficult choice. Choosing to bind the equipment would guarantee safety, but it also meant a loss in money. From the system's perspective, the system encouraged players to bind their equipment. Bound equipment would lose their value in the market, which meant that the system had taken it back. If the equipment was kept circulating, then the equipment would only continue to lose value with each new one that appeared out in the market.
