Flash light and blinding grenade effects and duration need to be fixed.

Ive played Delta force and this, both have blinding grenades both have flash light blind attachments, but it seems in this game the duration is to blow and the effect is to low. In Delta force when i get blinded by the flash light I can't see anything for a couple of seconds except a big white and black circle and it messes you up. That is how it should be. In the whole time Ive been playing since I bought it I haven't been blonded or enough that it matters. Ive aimed the sites straight in their faces and bit has done nothing   they still head shot me while I'm moving side to side and firing before them.
