Being red with Kusari trading factions would lead to too much trouble really when flying outside Bretonia on trading trips. It makes very tedious game play if I have to fight off NPCs all the time while trying to trade. However I would definately not mind to pick a fight in RP with some player Samura trader.

And a transport vs transport mud wrestling ensues;)
