I know those have been complaining about too much pew pew and well, nothing else. Too allow a bit of variety, why not allow a trader class of ships? Have them either be Federation, neutral, or Klingon faction.
Allow them to sell goods only available to them (making the goods get better as they level and put more skill points into trading skills). Allow enemy factions to kill them to earn some credits (maybe as a death penalty, since the traders would earn more money than other players). And not allow them to transwarp. Just have them flying through space and such. They can even sell their own goods from other characters, like a traveling AH. Missions would consist of trading to various outposts, outrunning raiders, etc. Allow them to only equip lower level weapons. Like if they were a Lt. Cmdr (of equivalent), they could only have Lt. weapons, and only specific ones. They would have an epically slow turn rate, so turrets for example.
