It used to be you chose between aggressive playstyles (T1, T3) and defensive ones (T2, T4)
you could mix and match however you liked.
First Relic removed elite infantry from T1 and made them call ins. Then they nerfed sniper cars because scrubs couldn't deal with it.
Then they made commanders with vehicle call ins that didn't require any tech structures. Is-2, kv8, kv1, kv2, etc etc.
Then they made t4 require t3 and then swapped the t-34/76 and su76.
Then they made t1 and t2 dirt cheap so you can get them both early in the game without slowing down later tech much.
As a result Soviet have way less tech decisions and strategies.
They were best when the game came out. It has been downhill ever since release for them.
This is with out out a doubt the dumbest post I have ever seen on this forum, soviets have less tech decisons and strategies? What crack are you smoking?
