It is not about even power between pieces but about keeping similar ratios between the same D6s unit and D8s unit. And if changing the ratio, knowing what and why.
For my part, I really like YG basic revised ground units because it keeps same absolute number on dice for AAA, Inf, MIs.
And make MI, Arty and Tank as cost effective on defense.
Infantry remains the best defensive cost wise.
Artys becomes the best cost effective weapon on offense, by itself and more when combining with Inf and MI.
This does not boost Tank (no odds change: 50%).
It is just that Inf and MIs are nerfed off/def.
But not when combined arms with Artillery.
Inf A1-2 D2
MI A1-2 D2
Arty A3 D2
Tank A4 D4
AAA A0 D1*
Purchasing Tank compared to MI will not be a sacrifice in defense, just costlier for the same odds cost wise.
And compared to Arty, it will be a sacrifice in offensive firepower for mobility and keep similar defense cost ratio.
It will allow more room for Soviet to purchase Tank to increase mobility compared to static defense with Infantry and Artys (no big sacrifice on defense, just on offense power).
Tacos? Tactical Bomber?
