That's nice. I'm not making an alt to buy a house on another server. I'm not leaving my friends and FC to buy a house on another server. Is it A solution? Yes. Is it an acceptable one? Absolutely not. And I will absolutely under no circumstances give SE the impression that it is acceptable by utilizing it. I will quit the game before doing so. Everyone that does it is one more person that is telling SE that it's a solution that they are okay with.
And instead of addressing the problem they continue to demonstrate gross incompetence in this area by dedicating resources that could be used to help address the problem toward new servers and a private island that I completely finished in less time than I've spent decorating my stupid apartment. Instead of adding supply to the places where demand has completely outstripped supply they decided they should add it somewhere else that has no demand whatsoever. EU with their half empty housing wards on the new servers is a wonderful example of why adding new servers isn't going to solve the problem. Oceania has issues with server population. People don't want to leave their community. Not in FFXIV, not in WoW, not in any game. The quiet majority of MMO players play in large part due to the social aspect. They don't raid, they might occasionally do a dungeon, but they mostly play to hang out with their friends. I don't know how many times game devs (not just SE) need to see this before they get it through their heads that anything that would make that more difficult doesn't work.
And the kicker is that they have yet to even publicly admit this is a problem. It is mind-boggling that the same devs that can do so many things better than any other MMO developer can be so incredibly inept in this area when others have managed to solve it over a decade ago. It's enough to make me want to smack my head into a brick wall in frustration.
