I was a witness of that situation. It was ridiculous and the undocking transport was far from innocent, but yeah, Admins have cast their verdict. I am just glad that it was not one of my Novas that scored the final percentage of damage.
How to solve?
> It has already partly been solved: 4h transport ban after pvp death
=> no danger that the same stupid transport will come in again and repeat his game
=> no need to keep him pinned down by pvping him all the time
=> no need for the transport to undock and provoke sanction material
=> no need for QQ and rage.
> Plus: disable the /shield off command or: Keep shields down for a real painful amount of time.
