I wasn't planning on rushing in this game, but this guy made me so mad.
I think he only got to 2nd Lieutenant because people fall prey to his cheeky strats (herding opponents herds away from his TC) and lameries (minutemen age1 ... the 6 guys oneshot normal vils).
Because he does NOT play good.
So since he put so much focus on my herds and frontline, I thought he probably isn't aware of his bases immediate surroundings. I put up an outpost to ship my units to, added a rax and proceeded to stomp him.
Hope this helps whomever encounters something like this - and hopefully you too win against such lame stuff.
