I wonder if it would be possible to make Arctic Future GvG and up to Virtual Era GvG. Right now once a player upgrades to the Arctic Future his/her Arc makes goods that guild doesn't need. In other words, the Arc loses its purpose and many players chose to stay in the Future Era. However, if there was a GvG map for higher eras, many more players would upgrade to higher eras, it would make the game more interesting and competitive. There still could be an All-Age map that would include a possibility to use units from every single age.
