Probably not. Ever since Abyssal Depths was introduced and player feedback has been given, the Marshals spawn has been an issue due to its very high DPS and especially damage application. EVERY other spawn added in that patch was addressed in some way by CCP. Drekavacs got their AI fixed, angels got their stats changed, sansha got their stats changed, kikimoras got some stat changes, and although theyre still really strong theyre manageable. Marshals (and EDENCOM too I think, but thats cuz the edencom rats are balanced, good job on CCP for making the edencom rats fairly balanced on the first try) got no changes since initial release though.
The abyssal community has repeatedly complained about how OP Marshals are, especially in regards to DPS and damage application. Each Marshal does 427.5 DPS and uses RHML, meaning they apply decently enough already to AB cruisers (or MWD HACs) unaided, but almost every Marshal spawn has webs and/or paints in the room, buffing the application massively.
The exact stats are that the explosion radius is 140m and the explosion velocity is 187.5m/s, and since they use navy heavy missiles the DRF is 0.682 (you can ignore all of that unless you wanna math out the application against a specific ship)
Against a typical Gila fit this means Marshals apply about 45% of their DPS without application support. However, when you add on some paints that gets buffed significantly, and if you get webbed you’re going to die unless you can face tank the DPS, which is 427.5 per marshal and a little extra from all the other rats. The damage type is thermal (except for if the marshal is named Drainer in which case it neuts 25GJ/s and does explosive damage instead), which is the only way its not even worse, cuz its the damage type you already wanna stack resists against cuz of the trigs. I feel bad for any Sacrileges though, because thermal is their native resist hole.
CCP however, has completely ignored the player feedback regarding Marshals and has done nothing. I can confidently say this is the ONLY thing that I have ever seen the abyssal community be completely unanimous on needing a nerf, and yet CCP doesn’t care. They’ve moved on from fixing the abyss and are onto whatever their next plans are. If we’re lucky the Marshals might get a nerf when abyssals get revisited in 2-5 years. So far the meta is still doing ok but Marshals are a huge pain in everyone’s side and bad enough RNG will simply kill you. I personally stopped running abyssals because of the Marshals spawn. It made my specific preferred filament, firestorms, completely unviable with a non-ultrablinged Gila since that weather nerfs thermal resists and gives no meaningful buff. The only thing that makes them ok is the dirt cheap filament, which is a sign that the filament sucks ass, and it sucks even more so now.
Sorry this kinda turned into a rant but hopefully you get the point. Marshals really need to get nerfed in either their DPS, their damage application, or the presence of webs/paints in the room.
