Usually the far ships are taken care of by the snipers, but this might mean a lack of DPS in tower bashes, or simply lack of fleet ship unity, which would sometimes cause lack of ships. As I see it, they are almost always 100 km away from the DPSes, which would mean if a special group of DPS would use MJDs to jump towards the far enemies it will replace snipers. After the group has been cleared they would jump back and continue with the rest of the fleet (since they do not have microwarpdrives they can jump the opposite direction, then warp directly to the anchor). They can be the new "snipers". With TCRCs a mobile depot could be placed at the end of the last site at the gate to the TCRC, where all the DPS could refit to MWDs and kill the dangerous enemy ships.
