The Cons of Option ④

The reason why I had a hard time choosing Option ④ was because of the following factors.

A: Players who belong to multiple communities might end up being torn apart by having to decide which community they will follow.
B: The option will cause stress on all players instead of causing stress on a number of players.
C: Players who decide to come back to the game after the merger will end up on a brand new World and no longer be able to player with friends.
What I like to hear what ever moved you to go with this?
Promoting a option and an explanation as for why this option was chosen over the others does usually not go by listing all the cons.

But then again I for one can not find any pro's in that option.
