I still have no clue what you are trying to say. You can’t warp gank alts onto someone in these sites. Even if the site isn’t at capacity, and even if the all the gank alts have sufficient standing to enter the site, they will still be warped to the acceleration gate, which they can take like normal and then would have to slowboat over to the target. That pretty means it is impossible for criminals to gank in these sites (the facpo will shoot them during the slowboat), and while neutral security status gankers could still try, anyone not sitting on the warp-in will have plenty of time to just warp away. Maybe a surprise suicide tackle from a “friendly” or unconventional suicide gank ships would catch someone out, but I imagine the standings grind alone will keep almost everyone from ever trying. Certainly it won’t be done casually or by a solo criminal.
That’s all perfectly fine. There are other mission spaces where criminals have much less freedom to operate and thus are much safer then hanging out unprotected in normal belts or on gates, but let’s not pretend that these Resource War sites will put you in any danger from the other players or are conducive for PvP. Almost no one will be ganked in them - the standing grind alone will ensure that - but given CCP Affinity’s assurance that they will only last minutes before collapsing, I don’t see that as a real problem. Players will be vulnerable entering and leaving sites, and while searching for them so 10 minutes of safety in the site still leaves some room for the hunters to catch their inattentive prey.
And no, I don’t agree with your final statement. It is trivial to operate safely in modern highsec. With perfect defensive play, you can operate in highsec at no risk to the other players. Only greed, inexperience, inattention, or extreme drunkenness will put you at risk of losing a ship in highsec. I have no fear of “those that want to prey” on me and I imagine you don’t really either given how much the game is stacked in your favour as a defender in highsec.
Good thing there are always a few greedy, complacent/new, lazy and/or drunk people to explode in highsec, or this would be a very boring game indeed for the highsec content creator.
