Not arguing with the Zenith being the best hull for nebulae. Plasma is beastly against shields and AI ships. Spire hull is pretty much a siege engine. Look at the other Spire capitol ships (FS line).
Which is why the Spire champion should be changed to reflect that, by making it
better than the others at being a siege engine.
Your speed changes make the Neinzul hull OP and completely destroys the viability of the Spire hull. If anything the human hulls could get a speed boost ability to accentuate the escort role.
Doubling the DPS of the spire hull and reducing its speed by about 30% would probably make it better, IMO. Changing its hull type to something that starbases didn't get a bonus against (which I added in an edit because the 'edit' menu didn't show your reply) on top of that would make it my ship of choice in Nebulas.
I don't think the Neinzul hull would become OP (in Nebulas, at least) with the changes I proposed, especially if weapon ranges weren't increased, but I'm less confident of that than I am that the Spire hull would become better. I would like the Neinzul hull to have a role in nebulas too.
The Spire hulls need the 2 on, 1 reload. That would put its damage above the Zenith hulls.
No, that wouldn't be enough, because the Zenith hull gets better modules. Doubling the damage value (thus doubling the DPS) and leaving modules the same gives the Spire champion the following DPS numbers vs starbases: (Old Zenith numbers included for comparison)
Hull \ size | frigate | destroyer | cruiser |
Spire vs Starbase | 1220 | 2190 | 3160 |
Zenith vs Starbase | 1260 | 2070 | 2880 |
The human champs main gun doesn't need to have a 5x vs "ships" since the hulls have a lot of light module slots. If you need to have those bonuses then load the appropriate modules.
I'm already assuming the appropriate bonuses, because without them, the Human champion is basically worthless.
Here is a comparison of the Human champion as-is Zenith champion as-is:
Hull \ size | frigate | destroyer | cruiser |
Human vs ships | 690 | 1110 | 1530 |
Zenith with no bonuses vs ships | 564 | 1026 | 1488 |
Zenith with no light modules vs Ships | 420 | 900 | 1320 |
Human with no bonuses vs ships | 354 | 606 | 858 |
I think it should be clear just how outclassed the Human champion is here, which is why I think it needs some buffs.
Here are the numbers including all modules with my proposed change to the Human champion's multipliers:
Hull \ size | frigate | destroyer | cruiser |
Zenith vs Ships | 900 | 1530 | 2160 |
Human vs ships | 1290 | 2310 | 3330 |
(Note that in all cases, light modules are assumed to get an x5 multiplier vs ships)
The limited speed and ranges of the champs force you to make hard choices. That's the point of the scenarios. Each hull has a use as it is now, and if anything, they might need a little tweaking. What you have here would require balancing of everything involved with the champs and scenarios.
If I had all hulls and all modules unlocked now, I would only ever use the Zenith hull in nebulas, and either the Neinzul or Zenith hull outside (because Insanity Inducers and cloaking are good, and so are drones and paralyzers).
At any hull class, I would prefer to enter a Nebula with max-level IREs and some combination of drones, shields, and missile launchers on a zenith hull over anything else that currently exists.
