Before the Burning Crusade, if you want some equipment, there was nothing except wait for monsters’ drop. It is true that sometimes you can also buy a bind on equipping items from the auction with wow gold or real money. But all in all, if you want something, you have to go brush, brush again and again to underground, hope that one day this equipment will be out, and hope you dice is big enough; if these propositions are not set up, you must continue to brush. If seven days a week, brush several times a day, the probability to get the right equipment is less.
With advent of TBC introducing the badge of justice, players are less subject to under the control of god, the god of destiny. In the DLC period, the new equipment in the merchant selling, and can be purchased with badges, means that the player can play a certain content repeatedly to have enough badges.
Wrath of the Lich King, badge system becomes increasingly complex; each level of raid has a corresponding new badge, used to buy new equipment. In the fission of the earth, therefore, in order to simplify various badges, introduces the points of two order system (justice and courage, and PVP honor and conquest points), the system has achieved some success. And now, we see in the riddle of the “panda” justice and courage points was surpassed by additional drop system, and the system will also be in the Warlords of Draenor be redesigned.
Additional drop mechanism of the next expansion may become more intelligent, but it have substantial distinction and points/badge system, not bought with points, but focus on item drops on the randomness of. By additional drop, you can get items what you want, or other an item, or only swtor credits, does not guarantee that you will be able to get what we can. As a result, its role is to bring back the “brush” element in the game, but it gives you another chance.
No matter what shape of the system finally is, Wow is not the pure already see a game of luck, and Warlords of Draenor seems to want to go further in the direction of the original, as players we can only wait and see.
