Way to go and cherry pick the points he made to suit your own argument and ignore the fact he said that Guards will let you last in the game UNTIL IS2 and T34/85 call ins to deal with late game threats, since you know late game tank call ins are pretty much the only thing this stale meta offers.
I didn't know the is2 and guards were in the same doc ether, you learn something new everyday. This isn't even an issue with guards but in efficient teching and units that make call-ins a effective choice
