Simply put, the people that are complaining about a quick scope have no idea what they're talking about. I'm not trying to belittle you, just saying you're misinformed. I've been sniping almost exclusively for the past 4 cod games and there's nothing easy about it.
It is the ONE facet of cod that you can't just instantly be decent at. You can grab an AR and do ok as a noob, you can use an SMG for the first time and do fine, same with shotguns and LMGs...but you cannot grab a sniper rifle for the first time, attempt to quick scope and be effective. Futhermore, any effective sniper uses quickscoping as a tool, not a play style.
Here are the real facts about sniping; Because of how powerful the automatic weapons are in most cod games (2-4 bullet kills), a sniper will only have ONE shot to kill you the vast majority of the time. In addition to only having the one shot he has to deal with flinch, which means that if your AR bullet hits him before he shoots, his gun will jump off target and miss. Also, it takes a fraction of the time to ADS with a reg gun as opposed to a sniper rifle even with quick draw on. Which isn't even considering that reg guns can hipfire spray you down. That means that an alert player will start shooting faster than a sniper 100% of the time. In addition to that, snipers typically play on a sensitivy that is 7+. Personally I use 9. And finally, a sniper can't walk and shoot at the same time. If he does the bullet path is random as if it were a no scope. All this together means that on 9 sensitivity, I have to come to a complete stop, line up my crosshairs to the target (which is usually moving), scope in and adjust if needed (drag scope) for EACH shot I take.
Meanwhile my SMG carrying opponent is staring at a mostly stationary target who he only has to hit once (because of the flinch) to assure a kill.
I understand it's frustrating, but the fact is that most snipers do poorly. This wouldn't be the case if it required no skill or practice You win way more gun fights with snipers that you lose, but it's the ones that you lose that you remember.
