I'd also suggest lowering the cost of base healing in at least manpower regards and/Or adding fuel or muni cost instead. Just food for thought.
In return Soviet early game is weak. I think one of the reasons is their Healing. It should be buffed.
The healing is getting a small buff with the medics QoL improvement, as the aura should help heal the large Soviet squads faster.
We are looking at decreasing the manpower cost of either the medic upgrade or T3 to give Soviet mid game teching an easier time.
