As I directly addressed above no one will do this. It is far too much effort to grind standing on gank alts just to shoot some random miner. Maybe some joker will pop a Venture in a low-tier site once in a while, but the top-tier sites that require hours and hours of grinding to just get into will be left alone by gankers or wardeccers. Anyone hunting someone in one of those will find it much more time- and cost- effective to try to catch them entering or leaving the site. And even if you did try to grind standings and gank as part of the fleet, you would quickly find that the other people in the site will warp off when you roll up with multiple “friendlies” in gank ships with active killrights and bounties on them.
It’s fine to have safer space in the game. I am not sure why you are so worked up about this. Just don’t pretend that you are at any real risk while in them from the other players. We haven’t seen the details, so maybe the new-AI controlled NPCs will serve as real risk or even open a window for a dedicated AWOXer to help the pirates (although I doubt this as this feature is an attempt to build a space for cooperative play and any such loophole that subverts that goal will be promptly patched out by CCP). But it is clear from what we know people in the sites are completely safe from the typical highsec casual violence perpetrated by the few remaining highsec antagonists.
I find it amusing when people who have clearly never committed a criminal act or hunted another player run around screaming that the sky is falling and people will get ganked with every new feature. There is not a ganker behind every asteroid in highsec and even if you are lucky enough to find one, doing almost anything will prevent them from hurting you. Unless you make yourself a very lucrative target to draw the interest of a professional organized group looking to take your stuff and brute force the punitive engagement mechanics with numbers, you are all but safe.
These sites are designed to be good at getting new players to group up and cooperate with other players, and bad at putting them in conflict with others, supporting PvP or driving competition. That’s fine as part of a NPE strategy but isn’t the conflict driver this game sorely needs. That’s ok, as there is other new PvE coming like FOBs and revamped events that possibly will serve this purpose.
How about you wait until we see the devblog on the other new PvE content before claiming the next expansion is going to be some sort of ganking massacre that is going to drive all the new players away? These are going to be some of, if not the safest sites in the game. Let’s hope CCP remembers that and the idea of risk vs. reward when they set the payouts and not fall to the temptation to over-reward them (like Incursions are) so more players do them and they can claim their new feature as a success.
