Housing and Island Sanctuary connected
I believe it would be better if we have the removal of the Housing system and just add it in Island Sanctuary. Basically everyone would need to be notified about the removal of housing in advance and have their items be in storage. Also players can choose which size they would want for their house in Island Sanctuary. Sadly this will also mean players need to complete Endwalker 6.0 and redecorate their House again. But I feel this a better decision in the long run. Plus players not only get their own house but thier own Island all in one package. With this addition players wouldn't want to leave their Island at all now :D
Hope its something the development team considers.
