Changes look very good to me.
Not sure why people complain. These changes don´t really go into the "make every faction the same" direction. They just make USF a better faction by making basic units easier to field. (MG and AT-gun)
First of all, i agree the changes to USF sounds very good. At least its pointing the right way.
Having said that i do agree with vipper too, and it simple to see.
OST techs and then builds.
SU techs building.
OKM techs deploying mobiles Sws on the field
USF has a premade base, techs through free squads
UKF has a premade base and has a half step tech system.
And i have seen many people complainting they want even more mirrored factions, only because they dont fit the factions style. Instead it should be the other way around, people embracing what a faction does best.
With this Ukf and Usf would be even more similar, ending up better for the latter since they get aggressive openings and free squads.
It doesnt bothers me that much, but a bit.
Still +1 to OP, tnx for your effort and will try the mod
