the difference is, MnK takes years of skill to get good. a controller can be put in a toddlers hands and because of how much hand holding you get on console over the last 10 years. He can get kills... But its ok, you'll never play on MnK and see the difference. you're just gonna suck AA off the rest of your life and think its skill... Its not your ability.
Now you might have good position and battle IQ aswell as sound recognition etc which makes you a better player, you use cover and dont run out in the open. Smart.
But the game aims for you, it tracks for you, You have no recoil you have no bloom. you have a button that insta 180s you. aslong as your crosshairs are near the person you're gonna win.
MnK is micro aim, If i dont burst at certain distances, or control recoil while keeping my dot ON you, im gonna lose. i have to do so many more things, you have to aim within 5 inches of me and pull the right trigger and thats viable at nearly every range.
