When I heard that GREE was allowing us to have up to 4 of these building I got excited. I thought to myself, "hey self, look on the bright side, now you can have 2 more than the other people so that you still have an IPH advantage because you played this game a certain way early on." But then GREE went and allowed everyone to have 4 of each which is retarded. They should have limited everyone to buying a max of 2 more of each building regardless of how many they already had. That way those of us who have them all and have an IPH advantage have the opportunity to keep it. Now everyone can have my IPH if they spend 2 vaults of gold. Just ridiculous.
