This is not pure my idea. I never played FFXI, but from opinions of others that I read it sounds like fun.
So the suggestion to dev is :
1) Add Moghouse = another kind of content
a) add / allow crafters to create and customize Moghouse (MG) parts, furniture, carpets, etc.
b) add / allow gatherers to find rare "Moghouse" material to later improvement
c) add 20/20 storage box for MG ( can be crafted ?) "for equip only", no other items can be stored
d) please feel free to post your opinions
* note :
I understand that battle fixes, ui improvements and content comes first. Anyway I hope this will be added to list next to chocobos ! :P
