Simple fixes are as follows:
1) FC must have existed for at least 30 days prior to purchasing plot
2) FC must have a minimum level of 5 before being able to purchase a small plot, Level 10 for medium plot, and level 15 for large plot. You cannot relocate to a plot that is larger than your current plot unless you meet the level requirements.
3) FC must have a minimum member count of 4 active people at any given time. The following criteria must be followed to be considered active:
- Must have been online in the last 30 days for at least 1 session of 15 minutes or more.
- Characters must be level 30 and above in at least one combat class to be considered active.
FCs that do not meet the 4 person criteria will be unable to purchase land. Demo Timers will be activated if the FC falls below 4 person criteria listed above. Furthermore, you will not be able to relocate while you have less than 4 active members. You will not be able to transfer Guild Ownership while having less than 4 active members.
4) FC leaders must have a minimum combat class LVL of 50. Characters cannot be passed Leadership if theyre under level 50.
5) You can only be leader of 1 FC per data center. You will be ineligible for transfer rights otherwise.
6) Ownership can only be passed once every 35 days. You can only relocate once every 35 days. These timers share the same CD - meaning if you transfer Ownership, you must also wait 35 days to relocate. Inversely, if you relocate, you must wait 35 days to transfer ownership.
7) Add a captcha like function when purchasing a plot (this is to combat bot purchases).
The goal ultimately isnt to make it impossible to game the system. I dont think that is a feasible goal. Rather, you could still sell an FC but the ability to do so becomes such a hassle that it isnt cost effective to do it.
As for legacy ownership, the easiest way to handle this is anyone who holds multiple properties on the same server (particularly multiple FCs), the demo timer will be initiated on ALL properties until the person only owns 1 FC per data center and 1 Personal house per server. If the owner transfers FC ownership to another player, the previous rules will kick in, and prevent the FC from being transferred back. Demo timers cease once a player is down to the property limits. With this system, it forces players to choose which properties they want to hold. And yes, you can actually lose ALL properties if the demo timer ends and you havent fulfilled the criteria required to keep a private house and an FC plot.
