No one is arguing about FC''s owning an entire ward. The singling out of grandfathering is wrong and debating that further with you is pointless. Asking them to give up their houses and all the hundreds of furniture items not to mention all the time to craft and acquire them is certainly unfair. They broke no rules and did simply what they were permitted to do at the time. Had alts been able to share a house (and they still can't) they'd probably never have bought them. SE made their decision and they won't be changing their mind and I don't find it unfair in the least. We've more than made our views known on the subject.
Fixing loopholes is another story when it comes to FC's and I don't think we disagree there. The owning of multiple FC's in my opinion is something new although I could be wrong. That started after the implementation of 4.2 and the restricting of private purchases to one per account and the implementation of the timer. At least I never heard of it as an issue before then. With respect to those multiple FC purchases I doubt it's an issue of trying to share a house with an alt but instead to try and either flip it for sale or gain access to multiple workshops for subs/airships and gardening for profit.
The workshop issue can be easily addressed in my view although I'm not a developer by decoupling workshops from FC and putting them at Grand Company as well. Gardening is another issue entirely because the dev team seems to have a problem with placing those in instanced areas like apartments.
