I looked at the lore that exists to get some ideas but its rather thin atleast as far as i can tell. Well in the game they have somewhat of a carrier focus that kinda goes down with the liberal application of conquest cruisers capitals. So i decided to give them a missle focus with the same reasoning that missiles (or composite) are kinda midline i guess
I looked through the forum at the first 100 hits searching for "Persean League". Here are some things that I found relevant:
Spoiler
http://fractalsoftworks.com/2017/08/16/a-true-and-accurate-history-of-the-persean-sector/ ... Persian league are the carrier faction, with fleets formed primarily around Herons and Drovers. Fighting them is a very different experience from fighting any other faction. Other factions use carriers too, but none nearly to the extent of the Persian League.
Midline seems to be the most common across factions that are not Pirates and some form of Ludd. ... Diktat, League, and Independents are very similar, although Diktat and League have some blueprints Independents do not have.
Now that's an easy round of "Spot the guy who met a Persean League Expedition Taskforce made up of two fleets worth of carriers!".
@ Alex: Not sure if this is a bug, but I noticed (after poking through game files) Persean League fleet commanders only have Officer Management skill like Pirates and Pathers, and not all four skills the other major factions have. I am not sure if this is a cut-and-paste error or deliberate design decision.
SWP adds it. In vanilla, PL just doesn't know Odysseys and can't spawn them.
Ah. I did think it was a bit odd that the mostly-mid-line (/w high-tech frigates) faction had so many high-tech capital ships.
Mayasuran Navy: I have not had a chance to play or interact with a lot of their ships outside the missions yet so I have no comments on balance. It adds a bunch of neat looking midline ships to the Persean League.
Also, the Commissioned Crews mod has this for PL:
Fighter Supremacy : Ship's nanoforges have been improved using pre-Collapse data, lowering the replacement time by (variable), depending on hull size. These nanoforges require less crew to operate, lowering skeleton crew requirement by (variable). Improves fighter replacement rate.
Altogether it seems that the "groupthink" wants the PL to be {carrier oriented discipline} & {midline majority with high tech minority}
You are wanting to add in ships that will bring even more missiles to bear, am I right? I would suggest those missiles be PD missiles like Swarmer (small) and Locust (large). The extra air superiority would allow the actual wings to get past the enemy fighters. You seem to be converting a lot of medium turrets to composite but there isn't any PD missile there. (unless you are planning to make one for this mod)
What the heck with all the Shielded Cargo holds?! I wouldn't do that, its unnecessary for a faction mod.
The Sunder isn't even a Sunder anymore, changing the Tech down to Midline & removing the system like that. It'd be better with the Hammerhead back to Accelerated Ammo Feeder and let your Sunder have Plasma Jets while returning it to High Tech.
