Let's have all infantry callins (shocks, guards, assgrens, osttruppen, irregulars, partisans, etc ...) show up at 0 1 or 2 cps. Most of the units are cost/cd balanced already (meaning shocks are better then assgrens but also cost more, osttruppen are cheap and weak but easily spam able, etc ...) so having them show up at the same time shouldn't be an issue. This may provide a semblance of equality rather than just screaming to have every soviet callin changed to 53 cps
We already managed to cry enough to get the kv8 and the is2 to come out at the same time (and approximately at the same time as the tiger) and if I'm not mistaken elefant guns and isu152s are the same as well right? Why not do it to infantry as well and call it good
