I swear my name here was the same (Mr Stalin)
I watched the replay again and my teamate was horrid, he lost nearly everything he built.
I have been trying different builds but the reason i like cons and a maxim because it builds well (if it more or less intact). I get gaurds, AT gun, maybe a support weapon if in a good position and then t70 etc. I feel like penals are a risky move and even if you get gaurds, you need to back tech for at gun which delays the t70s.
The maxium was a good choice in this case but you can see pretty clearly i fumbled my micro a few times which caused me to retreat. Other times its great with the quick set up time.
