Map Hack Alert !! All Chinese player use it ? (Absurd Game)

Really really boring and frustating !! Another "Absurd Game" vs a Chinese with a MAP HACK ... ... ... Rangers (x2) + US Mortar + US Scout is ENOUGH for him to reach all the map in 10 minutes and keep it during 17 minutes ... Just look at the camera !! => Almost no fights followed... Mortar shells fall down on units we cannot see ... Scout fog of far ... Anticipate the PaK40 shoot before he see it ... ... ... etc ... ... ... Relic, or anybody => What can we do !!!???
