I am all in favour of a nerf to Maxims, but Soviets T1 should be then made more viable, especially the M3A1 and considering the tier itself doesn't provide any AT tool (so you are subject to suffer against both Luchs and 222s and you are pretty much always forced to go Guards - which I think are overperforming when played correctly)
Just build the 160/20 T2...
You don't have to commit to one or the other. Getting both is pretty straightforward.
