@JustJohnny @Spingebill @butterdog i mean it's a multiplayer game and smoke grenades are part of the gameplay, it's one of the things that can provide tactical advantage and since it's a multiplayer game the visuals matter a lot, if it was a single player game and smoke just affected the AI no one would give two fucks about it.

Oh and another thing is that smoke is dynamic and can be i.e. blow away by explosions, which can nullify the tactical advantage with a tradeoff.
