Okay so i more or less finished my Valkyrian campaign and like a lot of people i consider them still too strong despite the recent nerfs.
One of the biggest weakness of the faction is their lack of mobility but i noticed it wasn't an actual issue for them. You can't flank those ships because of their very good shield coverage and the amount of PDs on the rear. All the combat ships with the exception of the Valkyrie MK.II have at least a 270° shield arc. On top of that, even the destroyers have at least 4 PDs to protect themselves against missiles.
Because of this, Valkyrians actually don't really have to fear of anyone getting in their back and for a faction which main weakness is the lack mobility, it's problematic.
But even then not every Valkyrians ships lack mobility, the Nirvana series and the Elysium have infernium drive that allow them to quickly move to a position to another. A lot of time i could go straight in the middle of the enemy fleet, delivering the killing blow to that one ship with my Nirvana and could get out relatively unscathed thanks to its ship system. In some way, the Nirvana/Elysium/Radiance are probably the only worthwhile flagship for the player as you can pull some very nice play with the infernium drive. The other ships? Not so much.
Another problem is their excessive amount of weapons. To compare an Elfheim and an Enforcer, the Enforcer have 5 medium mounts and 4 small ones. The Elfheim have 4 medium mounts, 6 small ones and 4 built in PDs guns. That's a lot more guns, especially when the Elfheim cost 10 deployment points just like the Enforcer and have much better stats in nearly every single categories.
Same thing for Cruisers, a Nirvana MK.I (for some reason i can't find a variant of it, even in dev mod) cost 17 deployment points like the Aurora but with 1 large mount, 8 medium mounts and 10 small ones. The Aurora only have 1 large mount, 3 medium and 9 small. The firepower difference is absolutely monstrous. In the campaign, i couldn't find a single cruiser that could go toe-to-toe with my Nirvana MK.II as i could drown it in missiles and bullets.
It's the same thing with nearly every Valkyrians ships, all heavily outgunning vanilla ships and keeping extremely good stats on top of this. Never in the campaign i felt strained by the the flux despite the amount of weapons i fire.
About the vanilla weapons combo with their ships. Most Valkyrian weapons deal energy damage but i think they benefit much more from Kinetic weaponry like the vanilla needler because they can instantly crush an enemy ship shield and open the way for their missiles. And Valkyrians have a lot of missiles.
A lancer/scorpion work but it doesn't work as well as a HVDs/annihilators combo in my opinion and experience. The Nirvana MK.II, with 4 medium and 3 small missiles mounts can spam Annihilators even better than an Onslaught and when you have 4 HVDs plus a MK.IX AC plowing your shield, there's not much an enemy cruiser (or even capital sometime) can do. But then again, it's not because Valkyrians weapons suck, it's because they have too much guns.
Still about the weapons, the IR-PD cannon is too strong. At 6 OPs, the IR-PD is a much better PD weapon than the dual MG, more ammo, more range... At every tests it took down more Pilums than the DMG did. A bit too good right now, especially when its built in some ships. The IR-PD laser however need two shots to take down a Pilum, it can intercept two lrms at best, sometimes 3 with expanded magazine.
In the end, Valkyrians have too many guns, way too many. Either you nerf their strength by reducing/removing some medium mounts, either you nerf their "weakness" by (heavily) reducing the shields arc and flux capacity/venting, or maybe a combination of both, given how strong they are it certainly won't kill them. They need to be vulnerable in some way. Right now missiles can't reach them and trying to crack them open with brute strength doesn't work either as they'll overwhelm your shield first.
Other than this, i found a few other issues.
As i said in the chat, the Legion lrm is broken. Infinite long range missiles will only lead to broken stuffs, if not for Valkyrian, then for another faction. They already have the Shadow lrm (although its range is surprisingly short for a lrm) that fill this role. The Legion really shouldn't exist, also it use II medium ballista sprite.
Speaking of sprite, the Ice lance have the same sprite as the concussion beam from Citadel, you might want to see this with Foxer.
The Scorpion MRM i think is a bit stronger than the Harpoon (more ammo which is better against frigates, faster missiles even though it's ROF is lower) but it's debatable. What is not debatable however is that the Scorpion is 2 OPs cheaper the Harpoon pod, not a good thing.
The Valkyrie MK.II is underpriced for such an incredible carrier. A mobile flight deck with two medium missiles and cheaper than an Condor? Hersey!
The Radiance redemption laser is too loud, like, uncomfortably loud.
A mistake in the Yoshura description "while its mobility is lacking" i think it should be "however its mobility is lacking".
The Ancord bomber CR cost is way too expensive. 20% per bomber deployed give it way too few replacement. By comparison a Trident wing is only 10%.
Also might be a good thing to add description to Infernium drive and Overcharge
I probably missed a lot of things but the main issue is here, too many guns, overall stats way too good. Nerfpls.
