IMO core world fleets should have hull alterations at some point after enough abyssal exploration.
Taskforces becoming AFK battles is kinda weird.
Legio Daemons with Hull alterations? Thank you, no.
I feel like some modded ships would go from strong to bonkers with some hull alterations O_o
Oh, for God's sake! Are you folks still afraid of Legio Daemons? How many times must I repeat myself?
My man, I don't know who you are.
Nor do we really know how legio daemons might be if they get hull alterations. I'm not afraid of daemons, but I respect them. I think they are hard, but (mostly) fair. Thinking there might be unintended or absurdly strong combinations of daemons and alterations is a legitimate concern and not one I'm willing to entertain in my game
Lastly, saying "combining hull alterations and daemons sounds like it could be problematic" =/= "I don't know how to deal with daemons! Please tell me all the ways to do it."
I get you're eager to help, but it's completely unwarranted and a little patronizing in this context.
Sorry if I often get myself carried away by zealous anti-Legio rant. Don't take me too seriously, really, as I only want you people to success in defeating the annoying Daemon toasters. That said, check the above post for some ideas as to which vessels to use to engage the vile Legio AI threat and easily gain the upper hand.
The best tactic is to use ships with GREAT ALPHA STRIKE DAMAGE, that is, when you fire all your weapons the enemy should become overwhelmed, or better yet, crippled. To that end, nothing better than phase ships since they reduce the cooldown time of weapons when moving through P-space. That means weapons with charges and/or high cooldown times, like phase/tachyon lances can fire more often, effectively increasing their nominal DPS.
This is the better approach, since Legio Daemons are REALLY TOUGH and must be eliminated quickly or they will overpower you. Move through the battlespace with impunity, emerging from P-space at the same time you activate the ship system to inflict high damage with energy weapons. The Percale Ambush Maneouvre, as I like to call it. Add to this the potential of ION WEAPONRY, which causes disruptions and flameouts to an otherwise very slippery and fast foe and they are marked for destruction. Ion pulsers, ion beams or their equivalent in the factions modiverse, notably the Scalar Tech Spindle arsenal. I suspect Nia created them as the natural counter to the Legio Infernalis, but other factions are also well equipped to face them in equal terms.
If you want to take on them with non phase vessels, you should procced with caution however. Be sure to ALWAYS bully them with a clear advantage in ship class: destroyer vs frigate, cruiser vs destroyer, capital vs cruiser, you know the drill. Overwhelming firepower, movility and speed are key, otherwise you are bound to get flanked by the hated Hel Retributions and Hel Kodais, who will inevitably pin you down until a Hel Scaith reaches the front line and engulfs you in fiery death. The Odyssey battlecruiser, with its plasma burn ship system is a better option to attack and retreat than a slow Paragon or Onslaught. Overwhelm them by flanking with your allies whenever possible, and swarm them with kinetic damage fighters like Broadswords to weaken their shields and their will to advance. ELIMINATE THE LESSER DAEMONS FIRST (this is vital) and surround the slower cruisers. Make them retreat to their corner of the battlespace WHILE YOU CAPTURE BATTLESPACE OBJECTIVES (also vital to ensure deployment points advantage) and hound them from all angles. Whenever possible, use efficient loadouts and flux management. Kinetic damage against shields with high explosive weapons kept in reserve until their shields are down etc...
Give it a try, first with a mostly phase vessels Excision Fleet and see how it goes. When you are confident enough, try the standard naval doctrine approach, with few or no phase ships but a balanced mix of fast and deadly destroyers, cruisers and battlecruisers supported by carriers.
