I did not watch it live, so don't know the context. After briefly watching it though, soviet t2 play counters Grens, which gave him map and things rolled from there. You got the better of squad wipes, but ran out of time. I have posted about this commander before, and the combo of t2/t4 and the T-34/85 makes it a very safe commander, along with strafe and conscript abilities.
The mortar halftrack did not pay off in time for you, call it rng or unit use from you. Personally I prefer the sniper to counter t2 play as I feel more in control of that then mortars and it forces a counter or them to rely on the mortar/rng.
That is my reading of it anyways. I don't think i'd label it terrible balance, but then without any context or elaboration in the original post *shrug*.
