USSR is one-role faction
*snips*
SOV has been demonstrated countless times to be the most resourceful, and the least predictable army of the game, mostly due to its open techtree, and most divers commanders. Sure, it does have a few bits that lack (T4 in general), but it is far away from being a one-role faction. But you said you don't care about ESL strategies and counterplay, as you called them "bunch of nerd tournament".
Stop throwing random keywords around. "Fair assymetrical balance"? Perhaps it does sound fancy to you, but that's it.
