*raises hand* Guilty as the way it was done (don't think it breaks TOS because its no longer possible) people would group with their main and their alt with someone else...DC their alt and login their main and send a friend request to their alt via the Party UI.

Honestly I think really if they wanted to solve a loss of resources without increasing overhead - simply restrict you to 1 house per DC and 1 FC ownership per DC.

To that extent you automatically are given full rights to ALL houses on your SA; so if I manage to land a house on Zalera; even if I am from Balmung - I can still make use of it - drastically reducing the issue of high pop servers. Furthermore and this is a bit of a ask -

+allow ALL alts to make a FC room in your FC as well as any FC you are part of. From a RP perspective it would save on the issue of IL as it would allow for stuff like bedrooms and such to be added to FCs

+require all multiple FC owners to "claim" one of their buildings and return all others to the lotto cycle - any submarines/airships and FC credits would be added to said FC (discarding the submarine limit or make it possible to buy more slots or grandfather it out)

+Put all FC chest items into the caretaker and allow for further expansion of the vault slots.

Really getting rid of the relevance of "what world your on" would go a great length to solving resource issues - as worlds are essentially just "instances" when we already have zone "instancing"
