One thing I would love to see in this game is a feature that allows you to attack ~something~ belonging to another player. Doesn't have to be their village, but we'll go with that.
So you have a 'defense' option when managing your village, which opens up more construction options for defensive buildings. You can station your troops, whatever. You can have it set up to steal resources, or do repairable damage to buildings, or... anything to make it worth while, but not so much that it becomes the only thing everyone is doing.
Or you could increase the bonuses guilds get for holding regions, and it can be those we fight over, as guilds taking on other guilds for control, not by influence, but by conquest... or raiding those guilds and stealing the bonuses for a duration, or something.
I am just throwing ideas... being able to attack player holdings in some form is probably the biggest thing missing in this game.
