You know the total number of plots available now? They're working to double that for 2.4, with the option to release many, many more because they know that what they currently have isn't enough. It was all they were able to release right now due to technical limitations.
Doubling it won't even be enough. There weren't enough wards for the FC's as it was - at least not at the affordable end of the spectrum. There's a few of the 40 mil ones on Balmung - I just took a cursory look to see if there was anything I could get.

Nope.

I don't understand why it was implemented this way. XI's mog houses were perfect in every way. They were instanced, people could come in and see, we could have our little flower pots to grow our ores, and we could decorate with all the cool things we collected during our gaming experience.

Instead of something like that, that even XI's hamster servers could handle, they want to just add more massive wards that will eventually cause the machines to buckle. And they WILL buckle.
