It seems to me that smoke does not entirely block LOS. I dump at least 2 smoke in between my infantry and an MG, but the MG still opens fire at me at the usual range. Same goes for AT.
Am I doing something wrong or does smoke just not work as it did in COH1?
My point is till, that I have the same wait and bad matchings as you. So whatever your rank, it does not hurt you more than it does me at positon 90.000-and whatnot.
