After reading this thread,
the conclusion is that Repair ships go to battles, supply ships over and over with nanos and bots. So, instead of nerfing them or extinct them, why not change its id and prevent them on enter and exiting a battle? If the flee they are out and can`t come back, and if they appear on a battle, they need to have a proper id and iff so they can follow the rule.
3.4 Fleeing from combat and then docking at a station or planet while you are in 10k range of the ship you were fighting counts as PvP death.Freighters and transports in this case may return to the system for the sole purpose of trading.
Or just remove the repair ship of freighter/transport class
