You didn't understood how it affected number of tanks. I explained.
Why do you think that I defending it?
I don't even care about its existance. I never use it, except maybe when I want to keep M20 on my base in case if I urgently need mines, but don't need M20 itself. Happens 1 in 20 games because I suck at unit preservation.
Ah ok then. I apologize for not understanding your intent.
