The problem snowballs in 2v2's, especially if your teammate decides that they are going to use your healing. It can be really annoying to see your teammate camped in your base waiting for his squads to heal while losing the map. I run into the same problem playing OKW so this isn't unique to Soviets.
But at least okw doesnt have to pay 250 mp for the heal, i would happily pay as soviet 125mp and 15 fuel instead, plust okw/ost have smaller sqad sizes and other (not as effective) sources of heal
