Housing has always been bad.

More people PvP now than previously. They already admitted that they overbuffed Black Mage, but that can't be the reason why "PvP has fallen apart."

Class design is a matter of opinion. I enjoy playing most classes, but I'm not everyone, and people can want different things from the game. I prefer simplicity so I could focus more on what's happening in a fight, where as other people want many buttons to press. Could things be better? Sure, there's always room for improvement.

Cosmetics/Customization is falling apart? What does this even mean? If you're talking about ear issues with Miqo'te and Hrothgar then I agree. On the other hand, they just unlocked gender requirements for a bunch of gear, and probably will do it for more later, which has greatly increased glamour options.
