I hope you guys have fun if this is really what you want, and don't just leave after a few months again because that left a massive hole in Idaho.
Personally I'm quite sad that you'll be inflating the numbers for this new world with the RU Whales, so they might believe this is something this community wants. You make a good point about new faces and old worlds getting boring, I believe closing the dead worlds and letting people migrate around a number of active worlds is the best solution, but obviously that won't happen any time soon.
As Raider said, I hope you'll choose to Join Colorado and after a few months of Russian Power Levelling, you'll be having way more fun battles than on a new world that the .NET fort fighters mostly won't play. We even have small battles at what I believe are Russian friendly times during the day and it should still be new faces and new challenges for your players.
But if not, enjoy sharing another world with TJ and proving me wrong lol.
