I would agree to this type of change, if it was limited to "line" ships only. Any specialty, command, or OOB ship that is killed or disengages suffers the full penalty. The line ships only half.
However, it hardly seems necessary, and I still don't understand the fuss of a few pilots over being banned form the single hex for the current length of time, as the map is big and there are plenty of other hexes to hit. Heck it is a 3-way server and thus 2 whole fronts worth of hexs to attack. The only rational I see for it is to allow for the cheese hex-flipping tactics where avoidance of PvP can win the hex. It makes it pointless to bother defending a hex without a disengagement rule, unless you resort to similar PvP avoidance tactics.
