I've played in Solo because I don't like the idea of being killed for no reason... I don't like Ganking!... Pirating on the other hand... I have Massive respect for clean pirates and I think it's one of the hardest skills in the game to master!
If the overhaul is C&P, I wish they would buff 'clean pirating, heist, smugglers' to the point of giving grades like 'Elite' badges and all... and make punishment for gank/griefing way more severe in non anarchy systems.
Quality pirating takes way more skill than it's given credit. In real life, killing victims is bad for business. Having the precision to shoot out engines without destroying the vehicle and then having to speed along side the victim in freefall, get in front of them, apply breaks and slow down their moving ship which now has reduced hull and no shields takes real talent. Not to mention you are often doing this with much lower protection than gankers because you need wake scanners, manifest scanners, FSD interdictors, cargo space, hatch breaker limpets, collector limpets, fuel scoops for chasing system jumpers... and a true gentleman Pirate also has repair limpets for the victim when the deed is done!
I am not anywhere near skilled enough to do this, but I have watched youtubers who specialize in being 'proper pirates' and it's like watching poetry... I would absolutely Always play in open if I knew an attack was survivable if I cooperated... most pirate ships are not capable of taking at most about 32-64 tons of cargo. I would absolutely be ok with those loses as a trader to be able to walk away from that alive. And it would not reduce the PvP aspect of the game cause most players are not gonna give up the cargo without a fight.
A simple algorithm could tell the difference between ganking and pirating... if the victim does not have cargo, no mission, no faction or other affiliation, is in a security rated system and does not deploy hardpoints, it's a gank! anything else is fair game to kill! same as NPC's do it. Limit gankers to anarchy systems
People playing together in open, to be able to go canyon running or SRV farming etc. in Shinrata or any other heavily populated systems... to be able to meet other players without constant fear of being attacked and destroyed for no reason... Is way more valuable to the games survivability than any other feature I can think of. I would guess there would be at least 10x more visible players in security systems.
