Assembly Hall

We can divide HACs into 4 categories:

1. Armor sniper (Zealot, artillery Muninn, rail Deimos, long range sentry Ishtar) (Zealot is fine, Muninn is mostly fine, Deimos just needs medium rails buffed, Ishtar as a sniper suffers from the caveats of sentry drones.)
2. Armor brawler (Sacrilege, autocannon Muninn, blaster Deimos, heavy drone Ishtar) (Sacrilege is underwhelming WRT the Drake, AC Muninn isn't of much use except in extreme niche scenarios, blaster Deimos can be good thanks to the hybrid buff, and the Brawltar could be a much handier ship in AHAC gangs than it is now I reckon.)
3. Skirmisher (Vagabond) (no changes needed)
4. Shield sniper (Cerb, Eagle) (These need much more extensive fixing, which probably should be the subject of a whole another thread.)

I'll start with the Muninn, in both its sniping and brawling configurations, as the fix is the same here: Trade one of the Muninn's utility highs for a low slot. This would allow it to fit a damage control, a plate, 2 hardeners, and 2 gyros subject to CPU/PG constraints, while still leaving a utility high available for countering tacklers with a neut and its drone bay intact, things that it both brings to the table as a sniper flying alongside Zealots. (Right now, you either drop the suitcase or a gyrostab due to the ship's shortage of lows and very asymmetric T2 Minmatar armor resists.) It would also make it more viable as a sigtanking AC brawler cruiser.

The Deimos used to be terrible, but has been helped significantly by the hybrid buff. It still isn't that great as a sniper, but that's a function of continued DPS issues with medium rails (they have poor DPS with respect to laser snipers and poor alpha compared to artilleries, leaving them with no niche except for extreme range cruiser sniping, which the Deimos doesn't mess with.) Unless an across-the-board medium rail buff is planned, the Deimos will retain the status quo.

The Ishtar is a solid PvE boat, but could use a bit of help as an anti-tackle platform or brawler in PvP simply by fixing its notoriously tight fittings. +5% each PG and CPU would be a good start, no? Other than that, the problems it sees in HAC gangs are the problems sentry drones face in PvP, aka you keep losing the buggers when you get chased off.

The Sacrilege probably could use the most help of the four, especially with the upcoming Drake changes. Upping the damage bonus to 7.5%/level and making it apply to both HMLs and HAMs would make it much more useful (allowing it to be competitive with HAM Drakes in brawling applications while still being able to hit out to a decent range with heavy missiles). The Assault Optimization subsystem for the Legion might (would?) receive a similar buff (that is, if an 11-effective-launcher HAM Legion is acceptable, which it might very well be, it'd put it on par with the Tengu for HAM DPS).

Cerb and Eagle need help, the rest are simply overshadowed by the overpowered BCs.

How about giving the Sacrilege a buff like it's little sister, the Vengeance just got, but with an extra lowslot instead of highslot? In that way you could fit an extra Ballistic Control System II, get better dps while still having a good tank. HAMs can stay as they are and the Sacrilege can still be specialized in close range brawling.

Exactly and DLAII uses up 55cpu. Combined with the reduction for drone rigs and the fact that all other drone mods are very CPU intensive makes fitting anything else in the highs tricky.

The Eagle needs completely repurposing. It's role as an extreme range sniper is completely eclipsed by the Naga. IMO the Eagle should be reworked as a "speed" ship rather than a "range" ship.

Armor sniping muninn rocks yo.
