sov arent on the backfoot because everywheere are cons behind sandbags. 222 comes at the same time as t70. before that you need a Pak which leads to 320 mp down the drain which cant fight inf and is only good for chasing off lv. and then that thing even misses....
Either you have quite bad 222, or god tier T70 timing. But no, Conscript sandbags usually not being spammed, unless the Soviet player does not get enough pressure. And if so, your PaK will come in even more handy and be able to take those out.
What's your solution then? PaK40 should hit every shot? How is the T70 buffed then if it can't really perform anymore as it has to? The Soviet player just spent 260 MP and 70 FU to finally pull slightly ahead in the AI game until mediums roll out.
I've just shown you that the PaK hits fairly reliably and is ALWAYS a threat for a vehicle that can take only three shots. Every T70 will retreat if it sees a set up PaK facing it, regardless of an occasional miss or not.
