I always see this in high level games where first 15 minutes-ish both sides are not willing to overextend, which makes sense because they are all good players.
But look at Kransky's build here. R,R,op,op,op,m8,S,S,howlie,howliwe,howlie
If i made a build like this i would get absolutely run over by vehicles.... How could you possibly stop a pack of ACs, puma/stugs, whatever, all coming in at once?
