Re: Smoke Grenades
I can tell you for a fact if you have not seen it already that the new smoke nades they are testing in 1.6 BETA are pretty cool. The smoke nade instantly exploded into a large smoke cloud and then trickles out some more smoke. Definitely good stuff.
As to the flashes. Yes would be nice if in addition to blinding you they leave you deaf or give you a slight ring in the ears. Seen the ringing done in the new Vietcong multiplayer demo. Though making someone deaf would probably be easier to do.
