Pirate battleship fits
Vindicator and Nestor have no fittings listed. Bhaalgorn only has obsolete fits (the ECCM module rather than a sensor booster with a script, for example). Putting something at all on their fittings pages would be beneficial. The others just have PvE fits of various sorts.
Note: I'm not including the Barghest here. Lore-wise, it's not really a pirate faction and the one fit on the wiki is a bit closer to how I'd expect to fit it.
Suggestions for Bhaalgorn fits to add:
1. Updated wormhole armor fit (the two fits on the wiki look like WHC Heavy Armor).
2. Wormhole shield fit (despite being generally an armor ship, pulsar systems provide enough of a neut bonus that they are devastatingly effective, without needing to train Minmatar skill beyond I to make full use in this context).
3. Null fleet fit. A lot of groups use Bhaalgorns because they aren't that much more expensive than T1 and provide excellent utility while still being able to put out eight turrets' worth of damage.
Fleet Nightmares (the first groups that come to mind which use these are Trigger Happy and Triumvirate, I've also seen them used in pulsar wormholes) should be looked at in order to add to the wiki in order to broaden since the recent controversy is because the page has been focused primarily on their use in Incursions without looking at much else. Small gang fits are another good idea.
Rattlesnakes have a few fits, but two of the main PVE uses of the hull (Null DED running and high-class wormhole ratting) are not covered. The C3 wormhole fit on the wiki would definitely not be able to handle a C5 anomaly. Additionally, there are a few groups with fleet doctrine fits, such as Rekking Crew.
Machariels also have a few more uses than just the missions fits that are on the wiki. Someone else can likely provide more than I know about Incursions. On top of this, the slot layout and versatility means that there's a pretty substantial variety of fleet doctrine fits for the Machariel. It can be either autocannon or artillery fit, shield or armor. Lots of groups have been making recent use of Machariel doctrines, including but not limited to Brave Collective, Pandemic Legion, ProviBloc, Rekking Crew, and Dock Workers, with many more having Machariel doctrines not in frequent use. Several of those even have multiple Machariel doctrines (for example, two nights ago on a fleet with Rekking Crew, it looked like Brave Collective pinged an autocannon shield Machariel fleet in response to what we were doing but some people accidentally brought artillery shield ships, while ProviBloc has both armor and shield doctrines that I've observed previously).
