So when it's turned OFF the game will have better tactics. Hardcore players do not want the run-and-gun senerio.
I play Hardcore only and I often run and gun, just so you know. I find it mildly annoying the way people word their opinions as if they have surveyed the views of everyone else and they are shared by all.
What makes you think they will change it from COD4?
The radar being turned off will not necessarily = more tactics. It could result in more camping than normally happens in HC matches. However, I'm not against the idea, but I doubt that they will change it.
