It makes killing everyone who has shield cells slower and/or more difficult which includes those who are not looking for PvP and fit shield cells. I do not see how it exclusively makes killing those not looking for PVP slower or more difficult.
I think people have already demonstrated pretty well the problems SCB's bring to how combat works, and I do not see how anything you wrote here really had anything to do with that...
I'm not sure why I would want piracy to be easier since I'm not a pirate but a low level trader... but yes, if the current state is that traders who are pirated are capable of always fleeing from pirates with the use of shield cells, then yes, that's a problem.
The current state of piracy is another discussion though... and a very deep problem IMO.
So your complaint is that fitting a tank makes it take longer to kill you? You do understand the purpose of fitting a tank don't you?
Obviously they are working as intended and the goal here should be adapting to the situation not crying for a nerf.
