Sorry to say, this won't happen. Simply put. It's been asked many times, however it's always turned down for the same reason as stated. Although the idea itself is a nice thought, it simply would end up draining the income from BD. Period. People will flock to it, other servers will suffer, and then in the end, people will ALWAYS want another no boosting era (which wouldn't occur). And people always suggest for a "pay to enter the world" version of this after this is stated. So, the answer to that is also no.
I know it seems like a great idea to even the playing field, but it really will only cause the end of the game you enjoy. If you find someone spending $100 thwarts you from winning, look for some active teammates to help you out. The one player everyone considers the "best" now-a-days doesn't even boost. It's just high activity and lots of planning. Activity will always prevail over boosting. It can even prevail over a boosting active player. I cannot state this enough. But the real question comes down to, how much are you willing to commit for that victory.
