Yea...raising the prices isn't going to fix the problem.

Players are unhappy with the housing system. How is making housing even more out of reach going to make them happier?

Yea sure less demand blah blah blah, but less demand does not equate to less unhappy players.

If SE want an even bigger disaster than the Shirogane launch to get the playerbase incredibly angry with them, significantly raising house prices would be a fantastic way to do it. It would be such a slap in the face to fix the difficulty in accessing content by making it even more difficult to access. That would essentially be SE saying "well if you can't afford it then you can't be unhappy about not having it".

And no I am not disagreeing because I have no house. I have had my house for years. I am disagreeing because it's a terrible idea.
