Is it necessary to have more WoW Gold?

Countless WoW players tell me that they hate wow gold sellers who advertise endlessly, email you lots of spams desperately, or suddenly ask you in chat channel "would you like to buy wow gold?" when you kill monsters with your friends. Those sellers speaking terrible English do not care about whom you are and what you are doing, they only want you to spend for their wow gold .
Do we need wow gold indeed? In the opinions of some players, wow gold is useless for them. or we can try to persuade blizzard to cancel wow gold (in fact, there have been many players suggested blizzard cancelling gold in Diablo 3), if we do that, those abominable wow gold seller will disappear, instead, there will be more real players participate in game, and we can focus on playing with great fun. However, is it the fact?
Let's take a look at Age of Conan and Warhammer Online published by EA. Age of Conan attracted lots of wow player when it was launched. FUNCOM are as cheerful as a lark about the growing number of online people 2 months before AOC was launched. Players are glad to see that there are more beautiful pictures, much sexier NPC and much violent and exciting scenes in AOC than in WoW, besides, AOC rarely cost gold. Gold is not essential for AOC players; except that it may cost little gold to build Guild Castle, there is almost no demand for gold in other time. But soon later, players became bored, because they have no more tasks to finish, no more maps for them to explore. They do not know what to buy with the gold they have, the only thing hey can do is to compete against each other. And some players choose to exit AOC in the end, coming back to wow. Continuously, more players abandon this game, for they no longer find fun in it. All servers except only few servers still operate in the world till now. I think that beside the imperfect bugs in AOC, the main reason leads to its failure is that those stupid Funcom fellow did not design gold as an interesting prop.
Then, let's talk about Warhammer Online of EA, I still remember what Mark Jacobs has written in his blog when Warhammer Online has just been launched--- "I HATE GOLD SELLERS WITH EVERY FIBER OF MY BEING. Well", He did what he said. Warhammer Online Glod is entirely useless in the game. Gold sellers seldom disturb Warhammer Online indeed, because few players will buy it, except he is a "game gold collector". Warhammer Online has the similar pictures to WoW, lots of tasks, plots and exciting RVR, however, the number of its players has been running down, which is out of EA's expectation. Why? The reason is very simple that the unvalued gold loses its fun for players.
Compared with Funcom and EA, blizzard is much cleverer. wow gold is used as a very useful prop, the more WoW Gold players have, the more pleasure can players get in game. Players enjoy spending gold in game, which will help them learn better skills, ride more beautiful Mounts. I have heard most interesting words: buying wow gold makes players lose pleasure in playing the game, just like giving you cash in our real life that makes you lose the happiness in the process of earning money. I do not want to deny this statement, but if somebody gives you money without any requirements, I believe that all of people will rob crazily, caring nothing about any pleasure.
Is there any way to buy cheap wow gold but avoid the disturbance of those boring wow gold sellers? My suggestion is to close the chat channel as soon as you enter into WOW, delete all spam in your mailbox, inform against sellers who peddle gold to GM. When you'd like to buy wow gold , visit some wow gold price comparison websites (MMOGoldService.com is recommended, for their most timely price information), in which you can find the cheapest wow gold and reliable gold sellers. I must realize that buying more wow gold saves me lots of boring time used to kill monsters, and makes me enjoy more pleasure in the game.
