This is the one gripe I have with this game. It seems to be more and more common for an alliance to buy an era. I know its important to support BD so the game remains free, but it is discouraging when you get worlds with mega boosters. As far as moving to a world without boosting alliances, its getting harder and harder to find one. I like the idea of boosting to support the game, I just wish people didn't feel the need to buy their wins.
