This includes teamgames. If you afraid of stuka/offmap wipping - don't use it but don't block the option for others.
I would be good if they added some sort of healing to the commander (replacing 1 model for a healer sound interesting)
1 model is utterly pointless, it will be enough to heal one squad at best, even 4 medics at sov HQ have serious problems keeping up with injured infantry in late game.
Besides if Commisar gets a retreat point it's only a matter of time before people start asking for same thing for OST.
If retreat point stays they simply need to give this doctrine a way to heal troops, otherwise its going to turn nasty in team games, I dont want Sov horde squatting near my forward assembly when playing Brits
