@audiofilomx I didn't say aim assist doesn't help, it's the only way controller can even imagine to compete with a mouse. I did say however that controllers have no advantage whatsoever against m+k, which was a wrong exaggeration.
Perhaps I should rephrase to controllers can have a few advantages, but are greatly outshined in most instances by a mouse.
Where did you find the 40% controller usage statistic? I couldn't find any source on the matter. It is impressive for sure, I would have guessed it doesn't even reach 5% (again, no source, it's an educated guess at best.) Still, even if 40% is the true number, that's nowhere near close to prevalent input method. It does show that aim assist is much stronger than I give it credit for however.
M+k has a higher skill ceiling than controller. Aim assist can only get you so far.
