I have been involved in POS bashes before, both as aggressor and defender. At one point I had a medium POS reinforced by a 10 man gang in a C1. I learned the benefits of multiple POS gunners and what you can do in the event of an eviction attempt. Evacuate the expensive non-pvp ready assets and find some more guns.
If you can make a 50 man fleet that is partly competent against an unsupported tower, you can reinforce a large tower, come back 42 hours later and finish the job.
I have little surprise that even in wormhole space, you can make a 50 man fleet that is partly competent to reinforce an unsupported medium citadel, repeat in 24 hours, then repeat in another 24 hours.
The time commitment (DPS grind) is less on a medium citadel, but there is a requirement to show up in a much smaller window 3 times. A successful defender is not left with the 'joy' of repairing guns while feeling incredibly skittish.
Looking at the current page of zkillboard for Astrahus : https://zkillboard.com/ship/35832/
- There are 40 unfit citadels that were stillborn, and died unfit.
- https://zkillboard.com/kill/54325101/ is a partially fit, nullsec industry rigged citadel, ganked by 101 pilots
- https://zkillboard.com/kill/54317387/ is a twin neut, wormhole pvp rigged citadel, ganked by 14 pilots with twin guardians. A Large POS may have survived this better. Nothing except tower fittings is visible on zkillboard as having dropped.
- https://zkillboard.com/kill/54288932/ has a token fit in highsec, ganked by 19 pilots.
- https://zkillboard.com/kill/54254569/ is another partially fit, industry rigged highsec citadel, ganked by 19 pilots.
Of all of these citadels, one had a reasonable shot of being defended. The rest? Unless you have a defense fleet, don't deploy a citadel with someone in local, or with open wormholes in Jspace. When I previously read zkillboard I was seeing similar ratios.
If you are ganking with 101 moderately competant pilots without a significant number of experienced defenders, I don't expect either a citadel or a POS to have much luck.
As a potential defender, I am somewhat concerned about loot drops out of citadels. I did however support the call that wormholes should not have the full known space safety rules (and a small part of me thinks that they should not in known space either). I do want better mechanisms for citadel owners to forcibly clean wormhole citadels occasionally. If, as a citadel owner, I am pro-active about keeping loot limited, I want the tools to do so. I have not checked what is visible outside the citadel during any citadel shutdown timer, but would want this to not be a call to loot for a full 7 days.
So far, ganking of empty citadels looks like 'content' rather than 'loot' motivation. Sufficient numbers are being generally brought so that it probably does not matter what structure is being lived in.
