So as mentioned in the patch notes I've just spent countless hours simulating the units against multiple factions in pitched and 1-1 battles etc and I think I'm finally getting close to the perfect balance done in this next patch, meaning the current photo used on the mod page is slightly out of date.

Results appear now more consistently as expected, though I might still tweak some campaign mechanics (cost to upgrade and train). If anyone has any feedback on the latest values let me know, thanks.
