Is the reason you won't use MNK because you know that it would not be advantageous to you?....that you'd lose the edge you have?
I'm not really sure what "standing up" has to do with anything because it's been proven time and again (through actual videos) that the recoil and bloom are virtually non-existent. Further, there are videos showing the reticle tracking enemy players for those using a controller.
I personally played with a controller (on a PC) one match just to see for myself. I found it was too easy to kill the enemy. As a side note, the only (ONLY) game I use a controller with is the driving soccer game...rhymes with Docket Fatigue....never play an FPS with it. Running and gunning, I had 18 kills and 18 deaths. I firmly believe that if I had camped some, or were playing on a console, that my KDR would have been greatly in the positive.
I love how console players (using a controller) will argue that it's a detriment playing on console with a controller because the tracking messes their aim up because the reticle drifts....which typically only happens in a chokepoint and doesn't really matter because in those situations, even MNK players are going to be holding the trigger down. From any distance, console with controller has laser beams and can shoot across the map....especially with SMG's and sniper rifles.
This is absolutely ridiculous! And, unacceptable. Which is exactly why I don't play this farce of a game anymore. Which is probably why the player numbers have dropped exponentially and lobbies have to be filled with bots. If the trend continues, online will become a single player game.
