I hate it has to come to this, there shouldnt be a poll since the answer is YES.
Thats part of what makes this game SOOOO enjoyable, its not like counterstrike where its all about how fast you can click upon seeing a person.
With INS just cause you see somebody, doesnt mean you take the shot. INS is for REALISM, reallife you dont just blow away anything that moves! You get on your radio, make tactics, check if thats your teamate. You gotta use tactics, not just run behind enemy lines.
Its a yes, and it needs to be on.
