Every ship in Eve is suppose to be disposable. It’s literally the first of the Golden Rules. I don’t know why players expect complete safety or to be immune to the other players because they chose to fly a more expensive ship.
Besides, a properly flown jump freighter is 100% safe. Between jumping tether-to-tether and the ability to jump out of any gate camp in highsec, it is impossible to lose a jump freighter unless you make a serious mistake. That is something that isn’t right and should be changed.
