I think it's a great change for making USF a bit less shaky in the early game versus OKW. I honestly doubt it'll have much weight beyond that, given long range DPS is totally unchanged, but its significant enough in that context alone.
Plus USF is going to need more early game power now that all their late-game indirect fire units got nerfed lol.
I am fine with changes against OKW, but this change would make the OST vs USF even harder to play. OST already have a very terrible early game power, and I don't want them to make it even worse.
