I took a look through many progression threads and learned some things. As far as I can tell no server has specified any sort of rules regarding cross server statics. Majority of servers do not track EX kills. A lot of servers do have a rule of 6/8 have to be in the same FC or LS to qualify as FC and LS groups respectively (although I don't know if this could be used as a qualifier that 6/8 have to be on the same server for it to be tracked) . A lot of threads haven't updated since the end of last year, both because there were no new kill reports or the OP stopped updating.
