My opinion:

-guild hall customization: if you're going to pay so much for a guild hall, the leader and officers should be able to decorate it and add a personal touch.
I like the idea of being able to have a guild logo or different wallpapers to decorate a guild hall with.

-guild daily messages: The leader and officers can set a message for the entire guild to see when they log on.
Yes, I would definetly use this feature, very useful.

-more faces: the selection is pretty limited
I'm personally not too bothered but I wouldn't mind the variety.

-practice dungeons: like normal dungeons, but kills and deaths don't count. They would just be for practicing combos.
Can't you just go into a lower level dungeon for that ?

-more pets
I kind of like having only a few pets to get because then players recognize them.

-male and female classes
I know that a lot of people would like to have a male mage or a female bear, it adds variety.

-houses: build and customize your own house!
Not that great of an idea. The house would serve what purpose? Waste of programmers time (IMO)
