Well, GvG is about more than just fighting in your age. The true strength of my city is in its versatility as I can switch to any age fighting or goods production, and a lot of it. I fight on all the provinces, fill pretty much any amount of sectors with defensive armies easily, have over 33k fights, have donate myself countless goods of all ages and medals and can do so at any time. I've also essentially built many traz's as I can slap down a bunch of PE goods buildings at any time and get someone the goods for it, so, in a way I've probably made more units than anyone in the game lol.
