Don't be so hard to T34 and SU85.
T34 is great to secure flanks while SU85 is amazing against Panthers, Tigers and KTs.
the T34 76 is more of a sweeper tank , to use against infantry and small armoured vehicles . Not a good tank against heavier german tanks ( panzer 4 with long barrel , panthers , tigers )
unless you use 4 or 5 t34s at a time .
