I think it would be cool if we had a new world that was dedicated to a new gamemode: WAR!
Players can join and create factions. Factions can have a leader, vice-leader, officials etc (just like towns).
There's a new type of townstone, the War Townstone. It can only be placed in the War world, it costs gold and it can't be expanded. You can also only place blocks inside a town.
Factions can be allies with eachother, like the way that people can add eachother as a friend ingame.
Players that aren't a member of a town/faction can raid enemy faction bases.
They can destroy blocks using the hammer (a new use for the item! ), but this takes a long time.
The raiders have to get to the townstone and stay there for 2 minutes, after this the town becomes theirs.
