Enemy visibilty

Ok this is just my personal opinion. but i think the ttk  and the ttd is way to fast.  i will tell you why. once again we have the enemy blending into the buildings, example the soldiers uniforms are brownish yellowish. so are the buildings lay down beside a building or on  a roof your camouflaged. Ran past a enemy laying by the side of a building killed me because i could not see him. It seems we have always had a problem with enemy recognition in bf. surely they could find a way  to distinguish enemies better than they do now.  for everyone not all players have perfect eyesight
