I mean, even PA itself is ridiculous. It's like SO, give you x2 vent, but also x2 weapon recharge, and it doesn't have any penalty like PPT or range.
A Ziggurat bullying non-Remnants
while somehow still needing to be propped up by a supporting fleet? Eh, I don't know what that's supposed to show, but it's the opposite of noteworthy.
This has very little to do with with Phase Anchor: the Ziggurat has always been more or less a cheat ship long before Phase Anchor was added this patch, and people have been soloing everything in the game using the ship since the day it was introduced. (The only debate has been whether it's more cost effective than the Doom, before the recent Mine Strike nerf anyway.) The Ziggurat is the quintessential "noob cannon" that's never seriously considered when it comes to discussions about balance or comparative builds, and a person would be laughed out the door if they tried to use the ship in one of the community AI fleetbuilding tournaments.
Just for fun, I dusted off the Ziggurat from storage, slapped on some weapons, respecced some skills, and visited a high danger system to hunt some Radiants:

without taking a single point of hull damage. Clearly the Ziggurat is a non-serious cheat ship, and a crutch to help new players defeat content they don't yet have the skill and experience for. It's not a useful basis of comparison for how Phase Anchor should function with phase ships collectively, other than noting that the Ziggurat is already so ridiculous that just as with Safety Overrides, capital ships shouldn't even have access to Phase Anchor to begin with.
Re: Phase AnchorSetting aside the Ziggurat, I think Phase Anchor is reasonably well-constrainted by the mount limitations of phase ships. Afflictors, Shades, and Gremlins only have access to small mounts, and AMB is the only non-missile small weapon that has the combination of long recharge and strong finishing ability to take advantage of Phase Anchor. Of course, AMB's tiny range and the weakness of frigate armor also makes these ships extremely impacted by the mobility restrictions from the recent Phase Field nerfs and thus they also really want the competing Adaptive Phase Coils, so this is a pretty fair tradeoff.
Harbingers and Dooms have more weapon options (up to mediums), but Phase Anchor doesn't really break either of them because the larger phase ships have such lower base speed that it can be hard for them to rush in and out of danger to take advantage of Phase Anchor - they tend to put themselves at risk doing so by running their hard flux up too high. It's really only with the large weapon options (Tach Lance, Autopulse, large Omegas, etc) where Phase Anchor's cooldown reduction boosts weapon performance to an oppressive extent, and weapon range also becomes long enough that there's not as much risk to hang out in-range and brawl with Phase Anchor; however, large weapons aren't generally available on phase ships.
The main outliers are Omega missiles, and not because of raw DPS: AMSRM and Resonators have great burst DPS but poor sustained DPS. Rather, it's because Omega missiles have such long range that there's no required exposure to danger for enjoying the flux/recharge bonuses of Phase Anchor, compared to the short range of other small/medium weapons with long recharge + strong finish. As I previously posted, this means that even the AI can easily pilot a phase ship to stay out of danger while milking Phase Anchor, completely risk-free:
https://www.youtube.com/watch?v=WvBXgxnwOw4The solution seems obvious: Phase Anchor should only boost ammo replenishment (reload) of non-missile weapons. (IMO, missile ammo reload shouldn't be affected by phase, Temporal Shell, or any other effects.) Note that I'm referring to the ammo reload and not to the refire delay - I think it's perfectly fine for Phase Anchor to burn through limited ammo faster on missiles like Typhoons. Of course this will also impact Pilum and Salamander use with Phase Anchor which... is not really a thing anyway. Yet.
