I've now played some 10h-ish with this mod, as Irsu. The lower armor is really punishing, especially when taking fire. I like it. Personally I think the dmg, mele def and attack are pretty good. I I had to be bold and make a suggestion I would maybe change charge and speed of different units. Making certain units suitable for certain things, say holding a live vs flanking vs chasing down fleeing enemies. I think that would make a good compensation for the lower armor, say they can instead flank or chase enemies. Imo. :)

Thanks for feedback :)
I will definetly work on unit speeds. Especially "charge speed" will get changes. A heavy unit with a small shield, has the charge speed of the fastest light unit. So disengaging from combat is simply not possible.
I'm still thinking what to do with unit stats, currently I'm just changing them slightly trying to make all units viable. But thats more like a bandaid. If I want to do it properly I would have to redo all melee stats from scratch, and doing that would take a lot of time.
