Russian Winter is completely negated by just not attacking Russia for a round. After that, it’s gone forever.
Non-Aggression is also completely negated by just setting up to kill an extra 4 infantry (not exactly hard.)
Think more critically. Both NAs as I previously mentioned and which you just verified both give Russia a full extra turn free from attacks. That is insane. I don’t know why you look at it like they can be negated by waiting a round, when that in fact is the whole point, to give you an extra round. What NAs actually do that? That’s a very good “temporary” bonus. That’s an extra round to crush Germany or build up more troops or whatever it is you do with a full round of income and movement.
Russian Rail is almost useless after Round 1 in most games.
Salvage hardly ever gets used, when it is, it’s probably while defending Moscow and odds are, Japan’s hitting you after that so you don’t get to use the extra tank against Germany.
Every nation has a couple of shitty NAs. I’m not exactly happy when I receive Mideast Oil + French Resistance, or Fast Moving Carriers + Island Bases. Banzai is pretty bad now, and Kamikaze is useless if there’s no KJF going on. Wolfpacks and Uboat interdiction are no good if it’s KGF since you don’t have the resources to build subs to hold the Allies at bay.
Mobile Industry is okay, but you have to have owned the land you move the IC too at the start of your round to build new units there.
There’s no buts, it’s a great NA. No IC in Caucasus to give to the Japanese is the whole point; and if you’re at the point where you’re retreating that IC from the Japanese, it’s likely that you don’t have the income to support more than 8 infantry anyways so it’s not like you’re relying on that mobile complex to build something.
I don’t know why you evaluate NAs effectiveness based solely on it being a one shot that’s gone later. That’s not good enough reason. If an NA was a one shot surefire attack on a capital, wouldn’t that be insanely good? You have to look at what the one shot does, not because it will be gone later.
