Guild majority power can be easily misused.

The last thing we need is infiltrator guilds that join sides to take over their keeps.
This could be used by players to grief opposing sides.
Join the enemy, make ghost guilds with no upgrades, and take control of them, then limit all the supply so no one can use it to repair under siege.
Instead of that, if a guild with more and better upgrades wants to take control of an already controlled location, they should be able to do so.
