There's no point at getting mad at people who own multiple houses.

The housing system needs to be fixed. One personal house/one FC house, per server, per account.

If Square Enix can't open enough wards to accommodate the majority of their active players, they should make housing instanced. Especially since the neighbourhoods are mostly empty anyway.

If Square Enix can't or won't make housing instanced in light of this, then I'd honestly prefer that they just remove housing entirely. There's no point to a gameplay feature that 90% of the playerbase can't access.

And just because I know someone's going to bring up the asinine argument, Savage raiding is not "a gameplay feature that 90% of the playerbase can't access". They're not the same thing.
