This is wrong only because it doesn’t work that way but I get what you’re saying although.
If you’re good at the game it shouldn’t matter if they’re MnK or Controller
While the extra aim assist tools the OP mentions do not do what he thinks they do. What it does & Id wager you know is, with a [b][i]actual 'proper'[/i][/b] premium config its a near 1:1 recreation of k&m but with the controller aim assist advantages. Not a slightly jank k&m input some claim it to be.
In addition to anti-recoil scripts.
Its cheating plain and simple.
Nope. not saying they can't. however MM does prioritize same input. if crossplay is on especially.
Since on console there is no native MnK support. If one was wanting to use MnK they'd have to play on PC and then would not be able to match with 'crossplay off' controller lobbies.
Bungie could add native MnK sup but that auto sets crossplay on and matches you against pc/ console MnK opponents.
