eRep could indeed start a second server but it's pointless, within a year the strength problem would be back. The original design didn't have this type of strength progression, they worsened the existing problem exponentially when they added levels to the training grounds.
In 1 year, a player can have 33k strength, which means you need 3 years to get to 50% of the current top players and another 3 years to get to 66%, then another 3 years to get to 75%, another 3 years to get to 80% at which point I think competition is viable. eRep only existed 7 years so far. So old players get an extremely unfair advantage over new players (Over 12 years headstart for playing 7 years). When I started, it took me 6 months to tag up to the 80% mark and eRep was already 3 years old. So in fact, this unfair advantage was built up during the last 3-4 years. So... let's rollback to the new server argument. After 1 year, the oldest players will have a 3 years advantage over the new players before needing to welcome them as competition. That's not going to make your game work.
I would rather play with more people then hang on to an unfair advantage (high strength) over a few people. All problems are linked in this game, not being able to compete in the military module drives new powergamers away, these are core to all activity in the game. Eventually you're left with two-clickers. The "clicking" you did for training was not "hard work" to gain an advantage over other players. Rank however is proof you did something in the game and could be used to be more significant in the battle module.
