Why?? ost has no easy/fast vehicle repair(repair station, crew repair, con repair) options like the sovs do. Also the airborne troops commander provides a forward reinforcement point with aura based healing supply drops. Where the hell is having advantage in one sector being offset by disadvantage in another spear going.
I dont see why thats relevant here. All the stuff you mention is doctrinal.
Sov have the largest squads but have no ai upgrades or nades nond doc for that readon imo.
Ost has panzer smoke healing and even a repair station in docs. Next to their 3 ways of healing ai upgrades and nades non doc. The fact that they repair longer is because theit t4 vehicles have more hp.
Peraonaly i would put an upgrade on the medics at t4 to go up to 6 medics for 250mp. Its not that soviets float mp so it should no be a no brainer that way. Or have the halftrack heal like the ost 251.
Edited my post, some words where missing.
