They tried to please everyone, but that doesn't work.
We now have THREE ways of progressing in gear: Dailies, LFR and normal/heroic raids.
They implemented this because they are so dedicated to their customers.
And we all know how that turned out..
The difference between a normal customer and a whiny WoW-customer is that a normal customer understands when something is optional.
Imagine the following scenario at an ISP-CS.
Customer: "I want to have the best internet available, but with your new highspeed connection you are forcing me to spend more money! I demand that you remove this product from your company."
That is exactly how those people on the WoW-forum are.
3 out of 10 times they aren't really genuine or insightful and 1 out of 10 times they actually DO miss it.
The difference is that a CM can answer those good topics once, but he has to lock/ban/respond to a troll all the time.
