It is worth, however, reiterating what is actually currently wrong with the EHP/DPS game and the current meta of POS warfare and structure grinds. Mostly this is so you are all aware, if you've somehow missed it, what's wrong and why it needs fixing. The how of fixing it is the contention.
Firstly, EHP is too high. Consider a small POS with minimal hardening. 10,000,000 Shield @ 25% = 12.5M EHP minimum if you aren't an idiot and you shoot for the lowest resist. If you pick the highest, 15M. The reason you even see blocking towers in wormholes (viz. offline towers anchored on every moon) and squatting towers in highsec (as before) is purely that it is the cheapest EHP in the universe. 55-80M ISK and 10M EHP. That's at least an hour's work for ten guys to pop one stick in high-DPS ships in order to clear away a blockade object that's preventing you either, respectively, putting up a siege tower or accessing a moon to anchor an industry POS in highsec. Plus if it's a squatting tower in highsec you need a wardec, which telescopes a threat 24 hours out, allowing the squatting tower owner to go so far as to potentially toss fuel and stront in all his sticks and prolong or prevent the whole shit show...or in fact call in "highsec PVPers" to assist the 1 man corp owning the towers.
If you start looking at bigger structures, such as a Dullstar fully hardened Dread Guristas Large with even 50% omni resists, 60M base shield HP becomes 90M EHP. To the majority of groups, that becomes a big fat nope even considering it goes into reinforced at 25%.
Our large tower has 80 sensor damps, 23 small beams, 8 ECMs (faction), 2 scrams (faction), 2 webs (faction) and flat 50% resists. Added all up, to incapacitate the guns is around 160M EHP and another 45M EHP to RF the tower. Sit down with 40 guys and waste a day, please. Therefore, basically impregnable only because of EHP.
This is an elephant in the room for keeping the current POS mechanisms and architecture - conflict is prevented entirely outside of building a dread in our wormhole (good luck) because I can cheaply pile on insane EHP. So, yes, the current system should change to some degree to prevent such egregious EHP walls (and that's not even getting to the heart of the defensive philosophy).
Remember where I mentioned you could anchor and online POS guns infinitely, even when your POS was reinforced? Well, that's just fucked. But it is apparently working as intended. The philosophy behind it is barking mad - to illegally quote a GM, it's to "allow the defenders a last ditch chance to defend their assets." by anchoring 50 large pulse batteries around a reinforced, crippled POS and online them one after another until the cows come home.
So. You take our 80 damp batteries, spend a shitload of wasted time incapping them, and then I deploy my strategic reserve of 40 large pulse batteries and 20 more ECM's and more damp batteries during the witching hour when you're mostly asleep. You wake up in the morning to a fully functional deathstar yet again, and have to contemplate reducing all of the guns to rubble again.
The new POS fitting will hopefully stop this. it depends if you can refit the guns on the fly using an orca, a DST or a Nestor (or some combo thereof) to fiddle-faddle the POS fit while it's deployed. It also depends whether the POS guns can be shot away or whether they cannot. But either way, the current system of infinite defence is just bullshit retarded - in my opinion, if your POS has been shot to pieces, your choices should be to let it burn or to repair the guns for defence, not just tack ever more guns on. This is why you see the Deathstar POSs with, no shit, 200 guns anchored around them. I honestly don't know why you'd bother - just keep the guns in a hangar array and deploy them as needed.
The solution is not Entosis
Sure, this sounds rightly bullshit. There is a reason we don't siege people out much anymore. Not only is it often unprofitable no matter how spendy the POS, how blingy the ships they fly and how idiotic their defences, because 90% of the time they just drive everything into a puddle of petrol and toss a match out the window - the whole process rarely results in a good fight. You maybe gank a couple of bombers, the odd Drake or hauler, and one weekend later you shoot up a few things and the POS, and if you're lucky make 250M from the deal. Sometimes they batphone and you get a good fight, most times the batphone is overwhelming and you scuttle away, time wasted.
Plus, more prosaically, if you siege out your prey completely, they may not come back and you can't gank them later. Tragedy of the commons.
So there are two ways it goes at the moment, barring a grudge match or mouthy cunts who make people angry. First, the idiots who you waste time sieging and get no fights from, even badly fit POSs have masses of EHP which turns a content generation exercise into a chore and a grind. Secondly, you have the professionally fit Deathstar, Dampstar and Dickstar POSs are too much of a PITA to attack, and Dullstars can go hang because....meh, boring.
The game balance problem is finding a level at which the new POSs, with their lesser numbers of guns maintain the same deterrent firepower and threat to an attacker, also become less egregious in EHP than the current ridiculous maxima achievable by cunning or half-informed people.
The new structures must be defensible enough that they aren't complete ten minute pushovers, whilst also not being impregnable due to massive EHP walls.
Entosis mechanisms will certainly resolve the EHP vs DPS problem, but it will make the POSs far too vulnerable, especially if the POS guns don't auto fire. Arguably, even by simply removing the guns themselves, you remove a huge chunk of EHP from the equation. In the case of my POS, it's 160M EHP. in anyone's book, that's a fucking huge amount of EHP which will just disappear. Sure, the POS itself might have 45M EHP, but that's achievable for most organisations of an equal size to Prolapse. who may consider attacking us for pew pew content creation.
It is also a huge barrier to casual faggotry and trolling. You have to invest some time blazing away at my POS, defenceless or not, before i become concerned. You have to be organised and committed and want a fight, versus just being bored.
To my mind, merely removing the POS guns and nixing the infinite defences, will pull POSs a lot closer to being in balance and less of a boring content creation exercise.
