I was thinking of this the other day actually. I'd love to see the Mog Houses return, but maybe without the Moogle. I'm not big on lore, but i've read they just don't belong in this FF for whatever reason. Possibly make it, so each storage chest is individually accessed in your MH, not a global storage count like in FFXI. So you can store armours in one chest, weapons in another etc.

But honestly, I just want to decorate again. That was half the fun of having a MH.
