Overall Khaaneph are a very interesting twist on Gaalsien,
Their Baserunner has alot more impact and influence on the field thanks to smoke and its blast drones, while their late game suffers due to their soft Carrier, inaccurate siege cruiser and weak scouting.
Some of this is warranted, however I feel Khaan is practically blind from a scouting prospective and their carrier can easily stumble into fights it cannot deal with.
So some changes I would propose.
Lv1-3 of regen system grant 5 armor per lv
This gives Khaan players some flexibility to mitigate incoming damage, as well as putting incentive into proactively using Regen, rather than just to top the carrier hp back up.
This also has the added effect of diverting power from the otherwise dominant missile system
Khaan carrier weapon system power grants vision bonus(shared with production cruisers)
The Khaan weapon system is the least used power system in the khaan carrier and for good reason, it powers a relatively weak missile launcher and 2 pds, there is very little to gain and there is no range system to combo it with.
Thus adding a sight range bonus and linking it to the PCs would open up a new and unique scouting tool while again drawing power from the typical mobility or missile systems.
Khaan siege cruiser regen nerf
The Khaan siege cruisers are largely in a good place, operating as a sort of assault cruiser with better long range abilities, however it is all too easy for a siege cruiser to survive an engagement and fully heal before any real follow up can finish it off, nerfing their regen would simply increase their downtime and increase the window of opportunity to eliminate them.
