Are you sure it's only 6 people?
Have we emailed the squads that have left and asked why? Where's the poll asking about this?
There was a poll done a year or two back and it was resoundingly in favor of moving the start time ahead one hour. So it appears the level of desire or fairness is not really a factor in the decision.
To me it only seems fair but maybe I am mistaken. In my opinion if I had to pick the ultimate start time for FSO it would be 8pm. Late enough that dinner is out of the way, rest of the family is probably chilling watching tv, etc.. But still would be able to be done by 10pm, very easy to manage that especially with the next day being Saturday. Hell I would even have no problem being up early to go hunting with an end time like that. The ideal time. So for the west coast backing it up an hour may make it a little less than ideal, have to rush dinner a little to make sure you are there in time or whatever. Why can't they bear a little of the inconvenience that us east coast guys are very much bearing (making it impossible for some of us, myself included to play FSO), which is still quite a bit more even with it being an hour earlier.
To me it seems only fair and based upon the last poll it was a very, very small minority that was not either for moving the starting time or had no issue with it being moved.
