My point was that even with shield and hull total hp being less than a mk 5 zenith starship. As long you maintain a healthy number of spire shipyard you can replace dreadnought at will with little risk to you. Zenith starship mk 5 fabricator on the other hand risk turned into "vaporware" in face of exo-waves.
They each have some pro and con. Spire Dreadnought can be flexible. Do you want lot of snipe shot that are immune to radar dampening? Doable. Do you want to burn something under that core shield? Plasma siege cannon done deal. Etc...
Zenith starship's weapon are fixed to only 4 hull bonus type and has no slot module to be flexible.
Base hull weapon for mk 5 zenith is about 400,000 damage per second. Spire Dreadnought base hull *no module* damage per secon is 4,800,000 a second assuming the beam hit the target for the entire 2 second beam is up. I would not compare them by just hull HP alone.
The Imperial Spire are supposed to be the
biggest superweapon -- the enemy that the AI spends most of its time fighting, rather than crushing your tiny empire.
Fallen Spire is supposed to be a
game changer. It's supposed to be a situation where the Galactic Capitol and its requisite cities puts you on even ground for a straight-up fight with
all the AI forces in the galaxy.
The Spire Dreadnought is
the most powerful ship you can get from the Fallen Spire campaign. Don't act like the product of a mere fabricator should be comparable to it.
Once Fallen Spire ships are where they should be (read: the frigate should be at least as good as a Spire Starship),
then consider whether it's appropriate for them to be transportable.

Also, Photon Lances generally only do full damage when you're outnumbered or facing stationary targets. I estimate maybe half a second of contact in a moving fight.
