This is a huge mistake. Splitting up the player population is going to seriously dwindle the interactivity between players and tribes. Instead of splitting up the population he should just spend the money and upgrade the servers =/
Part of xsyon apeal is the fact that there is a realistic world for everyone to interact...when you make 1-2 more servers it removes immersion..
Ofc i can make 1 char in each server but where is that immersive? why will i lose time creating 2 chars in a game like this where there is no endgame, its a continuous experience...for years to come...evolving in a world, creating stuff...splitting 5000 players its a bad move.
