Stock suggestion for Soviet:
Reduce the Power level of M3
Decrease power level.
Lower cost to 0-5 fuel, lower DPS, passenger no longer can shoot out of the vehicle.
Available upgrades:
"Drive by" cost 30-40 munition, passengers can now shoot out of the vehicle.
Other changes:
OKW get Faust at truck build not set up, generally OKW tech unlock should come with truck built not set since time varies from truck placement.
Passenger no longer die on vehicle destroyed, they receive RNG damage and stun or suppress.
Dead unit. Want rebalance? Or make it like bren carrier or make it like kuble (fast, cheap unit with recon for fast decap). With what you suggested it will be dead unit. You need spend 100 ammo to get ability shot from open-top vehicle from flamer? For squishy, low armored unit?
Penal
Decrease power level.
Cost down to 280 built time reduced, come with 4 mosin 2 SVT, satchel removed, PTRS removed. SVT profile changed to be good at mid but worse at max closer to M1 profile.
PTRS change to have lower reaction time.
Available upgrades:
"Research demolition charges" requires tech to unlock, gives access to demo for Penal and CE. CE can be re-balanced.
"AT upgrade" requires tech to unlock, gives access to PTRS AT satchel, AT satchel no longer causes critical only damage. At some a threshold was introduced so that vehicles would not run from infatry, there is little reason to have 1 shot engine engine damage available.
"AI upgrade" give 4 access to 4 SVT.
Personal preference, remove PTRS upgrade, introduce a separate AT dedicated AT squad like AT conscripts 2 PTRS AT grenades no ourah/merge, maybe "hit the ground" so it can still fire back vs AAHT. (The doctrinal option could improve this squad 3 PTRS camo and AT volley).
The higher cost from all mainline infantries and besides need building? 4 man? Need additional unique only for them upgrades? Downgraded version of grens, but with higher cost and with payable upgrades?
Conscripts:
Remove 7 men upgrade.
Available upgrades:
"Soviet conscription" available from t3 or T4 with a tech cost universals upgrade for all conscripts the XP/reinforcement bonuses only.
Personal preference, redesign Penal conscript as offensive/defensive infatry.
And they still need pay for upgrades lolotovs and at-nades as new penals? Right? Who will be mainline infantry for SU? Now you can play through cons, because you know that you can fight in late against vetted, upgraded axis infantry and don't lost map pressure. With these...i don't know. Only if your upgrade don't lock weapon slot and it's global (buy 1 time for all and for news guys too). But will want you deal with svt cons or ppsh cons with lower cost reinforcement?
T-70
Decrease power level.
Cheaper less lethal
How you will deal with axis infantry when they will got mg-42 adn stg-44?
M5 Qaud
Decrease power level.
Cheaper less lethal, reduce AA capability, possibly move suppression to separate upgrade or make it a timed ability.
Dead unit. It already have removed "on-moved suppresion", you need pay 90 muni for quad and another muni for supression? Maybe for flame-ht and flak-ht make the same? Fuel in fuel tank of flame-ht need to be repayed by muni. Want suppression for flak-ht pay muni. Don't you think that it will be dead units?
SU-76
Replace vet 1 tracking with barrage, Fix XP value.
How often you see current su-76 in games? I almost never. You can also rewatch 1vs1 tournament, try to find it.
SU-85
Replace vet 1 focus sight ability now scale with veterancy, providing less sight at vet 1. Vet bonuses overhaul.
How scale? Debuff still the same? How you want cahnge vet? Don't forget, su-85 - turretless TD. Only one stock armored unit in SU roster that can deal with panthers and KT.
T-34/76
Tone down MG damage, "ram" replace by "full speed" a "skill" shot making the tank move straight fast. At vet 1 it can "ram" on collision ability scales with veterancy.
And how you will be deal with infantry? How ram scales? It will be destroy enemy gun and engine on vet2,vet3? Or maybe only stun, but your tank also get stunned, but without cripple gun and engine?
Doctrinal changes:
Remove Radio intercept, IL strafe/Bombing, Mark target, ATG camo from IS-2/IS-152 commanders.
If this units remain so dominant they rest of the abilities should be weaker.
(same changes suggested for other factions.)
You want rebalance ALL factions in game and tones of commanders as well?
