More and more players don't have enough money to buy wow gold.
Blizzard introduced double-cd system which does not have any practical effect, but it will make the looking forward patch 4.3 became worse. More and more players don't have enough time to raid or enough money to buy wow gold as for the pressure from the job, family and the economic crisis. So, what should Blizzard do? Actually it is very simple.
First, stay the same.
4.3 is a last phase patch, the boss is patch 4.1 and 4.2, and plus 4.3 new three dungeons and random raid, the amount of boss will not like the amount at 4.1 patch be so stretched. And, the long-lost gold group may recover, trumpet could rekindle the flames of war. Then patch 4.3 will probably be oasis in the Cataclysm desert. The coming double cd may make the game more boring, and reduce game life expectancy.
More importantly, if we did not change, at least Blizzard can show the maverick, do the right thing what he thinks, and turning back, morally, generous mind to die. (After all, the patch 5.0 is still very attractive), but Blizzard has chosen to bow to the players, which lost the trail on a chip.
Second, abolish valor limit and increase valor exchange items.
In fact, valor limit always hamper the enthusiasm of the players, if you cancel the valor limit, we can predict that this will keep many players in the game. Furthermore, if there are more valor exchange items but not the best equipment, as long as a little toy, or nice clothes, or T1 ~ T10's old sets (after all, you can immediately change the shape of the equipment), this may lead more and more players come back to the game.
