well, there's exactly one german server, the jedi tower, that currently hits the 150people@fleet mark in the evenings, it's like the fatman, but sadly PvE. every other server is literally dead.

a good example would be jar'kai sword, the most populated pvp server. at least it used to be. nowadays it got 30 ppl on imperial fleet @ weekends.
