1 Plot per player is no where near strict enough.. IMO it should be 1 per Account!
allow all your account characters to access it and use it's facilities.. the fact players are allowed to own more than one is complete BS and punishes new players that should have access to all the games meta content without restriction and expanding wards to an infinite value. spawnable once a ward main and sub divisions are filled.
It's not like Square don't have the funds to create the a server infristructure to maintain this and take your thumbs outta your arse and get this done!
