Looking over the replacement for 3.13 on github as it stood a week ago, some notes for the proposed adjustments:
1) It looked like the following upgrade paths didn't make sense (to me at least).
Destroyer-Carrier-Missile Destroyer. Carriers were fine as a one-off unit and destroyers were fine in the path as it existed, they were just way too cheap. That's being addressed, but I'm not sure the path was a necessary adjustment.
Arques-Gatling Gun? What was wrong with Arques being a non-iron alternative in the chain and with gatling guns being simply a path straight up from crossbows?
I assume airborne upgrades to XCom, just didn't see it on the list given everything else being on there.
2) Longsword-Musket is fixed. Woot.
3) Unit cost/stat changes
It looked like "vanguard" infantry units discount is being removed, but their strength was also increased (roughly 10-15%). The main change to the assault units would be access to the siege promotion, I think they were fine in strength and the "discount" would be they don't require resources where swords did.
The changes to the gatling through bazooka line look fine stat wise. They may not need a discount to be worthwhile... if the gunpowder attack units alongside them aren't buffed in strength.
XCOM unit seems absurdly strong now (155?)
There also appears to be a return of the defence promotion on the spear-pike line. This might be okay in relative terms to balance against mounted and ranged units it's just strange that it also applies to arques.
