What is Old School mode anyway?
And on a side note, not directed necessarily directed at you OP, but I am so fatigued at hearing people complain about teens and tweens playing MW. Just mute everyone. And whining about perks being abused and kill streaks etc... *sigh* just get better or stop playing. YES, it can be infinitely annoying to have 3 helicopters and air strikes destroying your team but just as many times it swings in your favor and you crush the opponents.
I'm not saying you can't yearn for the days of old, when FPS games were a gentleman's affair online, where instead of some 14 year old calling you a "fag" you had some neo-nazi comparing his team's prowess to upcoming the Fourth Reich via text because voice chat wasn't around yet. But honestly, this is how it is now and it's all those teens fueling these blockbuster hits so why focus on you?
