Dude here is the most annoying thing ,he build simcity near every victory point ,i try to run down and up, but they always held atleast 2 victory point so yeah my time it kind of limitted.Since they got a wall of camping to fall back to safety and lock down that sector they just send cheap tank and infantry to blow out the def units at our point, mostly just had 1 mg defending but yeah maybe that where i go wrong i should had locked down the point that i already got.
It is rather map depended but making many emplacement means that your opponent has limited tech and his has a small mobile force.
Thus one has to defend his own VP and attack areas with no emplacements first.
