What, you don't know about how fruitless Ost/Soviet T3 is in general right now? How it's much, much safer to spam call-ins than commit resources to late game tech/units? You need to catch up.
I don't understand the statement you're making when you cite the lack of "safety" of T3 and then go on to talk about "commit[ting] resources to late game tech/units". I don't get the point you're trying to make.
