EDIT: I swear I saw a post dated 2005, saying "This was a good idea, but nobody ever gave it consideration", which is now deleted...
Because it doesn't matter if he never renames a country the same name it had once, ever again. Even if he says "okay bish are now octagons" then those that are so pig-headed and stubborn to change teams to even things out will all just arbitrarily pick the team they all want to be on, as a whole.
So changing the names does squat. Does nothing. You still have the same unbalanced horde mentality, just with different names.
A rose is a rose is a rose, etc.
That idea did nothing to help solve the solution, and only perpetuated the problem "in place" of eny restrictions -- basically you might read it as a "I hate ENY I wanna fly my plane I pay my sub waaaahh!!!" thread.
He's basically saying "remove ENY and just rename the countries every map rotation" -- which does nothing at all, which is to say he's just saying "gimme my plane back!"
