Molotovs are 50% cheaper to trow and OKW gets side teching in new patch anyway.
Hey, does the OKW need a specific tech upgrade to be able to throw Molotovs and another specific tech upgrade to fire a faust? no
At the very least, Soviet's At grenade and molotovs should be merged into a 250 Manpower, 20 Fuel Upgrade, and possibly add a 3rd tech to fill the empty HQ upgrade space requiring T4 called Soviet Industry that boosts vehicle production in the late game.
