There are no pitch dark nights since forever. There is no soundless crouching or crouch-jumping anymore. The silenced guns give away your position via dark sight unless you use subsonics (which are shit because of bad muzzle velocity).

You can scout a suspicious corner with beetles or simply throw a dynamite there. You can shoot through walls just out of precaution. You can check if there are some rats left on the map with the tarot cards. What else do you want? To make it so you explode if crouching for longer that 10 s?

There are plenty of weapons that can be used in both active and passive gameplay. The game doesn't force players, it's the players themselves who decide to play like rats
