Just how legit is using a controller to play MS?

You're missing the point. Tons of people bot and think they're legit. I want to read their logic and reasoning for this.

I can explain a few things about a controller that give the player the upper hand:
Comfort, players can last longer on a controller
Complex Macros, with the use of the profile programs most tasks can be [INDENT][/INDENT]simplified to a button
Better control.

The legit or not argument is the bane of many idiots that play this game. People cheat in life all the time. Talking about it will get you no where and you have no power at all in the situation so why waste your breath?

Logic and reasoning, I'll throw you a bone. Anyone who can exploit a loophole with little to no consequence will. Anyone that has a chance to have an advantage will take that opportunity. Anyone who can have the same option with a lower cost will. Out of the masses the majority will do these. There is no point in frustrating yourself with a question you have already answered.

You might as well say that having an advantage over a player is illegit. That can be argued but won't go far. Either way stop wasting your time with such a stupid topic; the only possible benefit you can get out of this would be reflection some time later but please stop embarrassing yourself.
