You are so wrong here...
And which commander feature that would be you've mentioned?
Dual t-34/85 call in. Then I bought it, it's description said that I will get two of them. Considering this, abandoned theater of war and the fact that relic already screwed the users, who bought commanders, skins and other additional paid stuff then they switched to war spoils, I think that relic doing something wrong here.
Any way, I can't see how making m4e8 and t-34/85 require t4 and be callable instead of requiring t4 and be buildable will change balance in significant way.
