The attackers and defenders have the same tools available to them. That having the same tools as the opposition is "not fair" because no-one needs to present themselves to be shot at is just another "this game feature that doesn't require any player to engage in PvP (in a game where other players, and therefore PvP, are an optional extra) is not fair because I can't shoot at players who engage in it" argument, i.e. it's perceived to be unfair by those who don't accept that no-one needs to play with them to affect game features.
I expect Frontier know - but they're not telling.
Thats the problem- one mode (well, two) dictate the pace of the game, and that activities such as hauling fortification are never stopped by PvE NPCS but are via players when they should.
Plus, as it currently stands "attackers and defenders have the same tools available to them" is not really true. Attacking is very difficult while defence very easy via non game ways.
For example- fortification is automatically won if the defender reaches 100% regardless of what an attacker has done. Defence (although pot luck sometimes via 5C) is made easy via the consolidation mechanic and attackers can do nothing about it. Prep races
have to be done via haul races, when destroying haulers would be one way to slow your enemy and give your haulers an advantage. PP BGS work (in a BGS that makes direct aggressive moves difficult) stacks the deck even further. Lastly the defender has maths on thier side, because systems fall off in turmoil in a specific order, meaning a lot of the time attacks have to be overwhelming. And even then the UI instantly alerts defenders to an attack, so one slip and that effort is wasted.....and if you
are lucky and unnoticed even at 100% undermining sometimes
nothing will fall off. This does not include PG farming, where merit bombs can be gathered at leisure.
In a feature where intercepting vital cargo and traversing 'dangerous' enemy territory is rendered pointless via modes, Open well, opens it up. Suddenly station proximity, ship type, defences, pilot skill, teamwork, nerve etc all become important. Using smaller, faster ships increases suitability but increases the amount of runs required. Attackers can seriously mess up a rival directly, or come across suspect activity.

Well they did, twice (well, 2.5 times via weighting) all via Sandro with three proposals. I'd pay good money to know what FD think now and 2023 might be that time.
