Suppression shouldn't even be a thing.
If you get shot at in real life, your aim doesn't just magically start swaying around. And your vision doesn't go blurry (okay maybe if you're being bombed you'll be shaking from the shockwave).
I get the "artistic" effect of being shot at but yea... it's definitely too much and not fun. Especially because you have to run 5x more in Sandstorm than in Source to get to the objective because everything is spread out more.
Suppression is a necessary mechanic (that mirrors reality) that makes firing at enemies meaningful. LMGs are damn near useless in their intended role with it. Dont run so much, you'll live longer.
Also, have you ever been shot at in real life? Do you have friends who have? No? Then stop acting like an authority on what happens in real combat.
If you ask anyone who has had gunfire close to their head, it DOES blur your vision for a split second. Unless they're firing subsonic ammo, the bullet creates a sonic boom next to the target when it passes causing a momentary blur of vision and a loud snap near where it traveled. And the equivalent of your aim getting fucked up happens too. You duck, you move, you do something when that happens near you. You don't hear bullets crack beside your head and think its a good idea to stay out there. INS is much nicer about bullets than reality. I don't need Sandstorm to be reality, but don't claim that you know what it's like.
Sorry to come off a tad salty but its obvious you don't know what you are talking about.
