You're blaming Treyarch for making a game in current technologies? What game or film doesn't use surround sound since about 5 years ago?
Most games won't give you an advantage just for spending $150+ on a headset.
How is it anything like bribing a referee. Just because you have a headset does not mean you will win.
The advantage it gives you means 9 times out of 10 in a 1 vs 1 situation the guy with the headset will win.
There's a reason MLG players all use headset; they'd have no chance if they didn't.
That's on par with saying people with a HDMI telly are morally wrong because those with 576i can't see people as well in the distance
I actually don't know anyone in the situation you described, but that's probably because HD is the modern standard. 5.1 is just an (expensive) accessory.
having a headset is no more wrong then having faster car then your next door neighbour
It would be if you had a drag race(something actually competitive).
If you feel it's unfair and so much of game - save up and buy one. I made a thread on the gains from just using a pretty good pair of headphones.
Believe me I'm going to if Treyarch fix the sound-whoring, as I'll have no choice.
My k/d from SnD over the last 3 days(in BO) has been over 3.00, I have no doubt that if sound-whoring had been going on it would be well under 2.00. Just goes to prove that the most un-skilled of players can become instantly successful in-game by spending money on a headset.
But as I said; if Treyarch tries to fix sound-whoring I'll have no choice but to buy a headset. Sucks but if you can't beat them, join them.
