use tier 4 then. i find it a bit disturbing how many soviet players beleive that one tier should solve all problems. the enitre faction is build around its commander + a cerain tier. i expect osme combined arms and skill from te soviet player to knock out a german heavy and not a spammable all rounder.
And I find it disturbing how many german only players believe that soviets can have T3 and T4 in one game unless it lasts 50+ minutes.
If you've went for strat that involves T3, then he will not have T4.
"Just using T4" is also no solution. Its extremely boring and extremely map dependent, unless you want to return to times where it was all about guards+M3 snipers to SU-85 spam, because I certainly don't.
