i think you need to enlighten the entire community on how to play during blizzards then because you seem to be the only one who gets it.
Gain vision over your opponent. This can be done through flares or garrisoned halftracks. (Units inside see further than units out in blizzard) Use smoke barrages to make key targets less useful. Use fire pits near the front to warm your troops up before assaulting with pgrens/shock troops. (It takes time to get cold.)
Or just spread to the corners of the map and take territory. Using troop transports you can strike multiple areas of the map very quickly depriving your opponent of territory. Destroying firepits at your opponents natural resources also make recapture more difficult for him. By seizing the initiative, counterattack becomes more difficult since he has to leave the safety of his firepits. Meanwhile you can get back in the halftrack and drive off after he waltzes all over to you and then attack the part of the map he just left.
Soviets in particular were very good in blizzards due to their flare veterancy abilities on the sniper and mortar and their recon ability on t70/t34. Germans however had the advantage of bunkers, earlier halftrack and scout car vet ability detecting infantry.
OKW had the flash light halftrack and kubel wagon vet 1 ability for their own blizzard detection, Americans had smoke rifle nades and fighting positions but had troubles remaining mobile during blizzards. (Which is fine, because normally they are spread all over the map and blizzards ended up isolating their squads forcing them to consolidate a bit more than usual.)
If you honestly took advantage of your opponent hunkering down, you could seize huge swathes of the map during blizzards. It also gave you an advantage if you scouted his position before attacking him. It shook up match up dynamics, putting Ostheer/Americans on their backfoot while giving Soviets/OKW new opportunities for map control.
The original Soviet/Ostheer match up is one of the most interesting in the game during blizzards because of how the factions were designed. Without blizzards the match up is less interesting, and units like the t34/76 had to be buffed significantly. (The soviet tech versatility also got neutered.)
