Uhm not to be mean or anything, but you should be making up statistics. I highly doubt that 90+% of players are experiencing problems, and from what you described it seems like you aren't either. Now I'm assuming you're playing on a ps3 (due to the site we're on), so weapon hacks, whatever you are referring to, shouldn't be a problem.
Spawning is not really an issue unless you get into maps like nuketown, but otherwise the game usually does a pretty good job of spawning you far enough from an enemy that you have time to get your bearings. You also might want to read the Steady Aim description more carefully, because Steady Aim does nothing to stop you from shaking when ADS firing. It only makes the aiming reticule smaller when you're firing from the hip.
Pro Tip: Fire in bursts, only tapping the fire button, or switch to a weapon with less recoil if you can't use the one you're playing with now. And as for run and gun gameplay, you bought a call of duty game, that all the multiplayer ever was lol. You can use a sniper if you want I suppose, but the majority of players are just gonna run around getting a lot more kills then you with an AR or a sub-machine gun.
Now, I'll give you that the pack is way overpriced, but I have to disagree that MW2 felt more consistent. Not sure if you recall, but MW2 was plagued with infinite killstreak spawning, thousands of campers trying to get a nuke, severely overpowered weapons, and the worst hit detection I've seen in any game. The hit detection was so bad I would aim at a crouched guy's head who was sitting still, with a sniper, pull the trigger and not even get a hit marker.
Personally, this game is infinitely better than MW2, and the only thing they really need to change is take the grip off the AK74u.
