Alliance Management.
Say you join an Alliance. You get to know the people, you donate your way to the top, even become a Vice for your hard work and efforts. You than hear a rumor that your leader might be trying to sell his alliance, something a lot of people put hard work into. Maybe he doesn't want to ben in an alliance, maybe he's bored, who knows. My point is maybe you can make a way for the all the vices put together to either take command and nominate another leader, or put the leader out entirely. Now mind you I said "all" vices, so there's little chance of abuse. Think about it. There's got to be something that can be done to prevent future great alliances from crashing.
