Yeah; it would piss off a bunch of people for effectively zero gain. There's no way we could get the density of other islands up by sinking the Colonies.
So, JDodger, let me turn this around on you.
Why do you think sinking the Colonies would be a good thing? What would BattleMaster gain from it?
Because that's always what we have to consider when doing something drastic like sinking an island. It's never, ever a matter of "is there a good reason not to?" first. Because there's always a good reason not to: the enjoyment of the people playing there, some of whom have had characters there going back a decade and a half.
