I agree. SWTOR and FFXIV also launched with only 2-3 housing locations.
Housing is an evergreen system. Just get it out there and add a bit to it with every patch.

Housing is about the most useful use of resources they can do. An evergreen system that will see content constantly added to the game. A raid tier is cleared in 2 weeks, farmed for 5-6 months and it's done. Housing is till the end of the game.
