Mouse and keyboard - cheating

I’m getting increasingly frustrated by people using third party hardware to use a mouse input to play Halo 5 on Xbox. It’s obviously gives them a huge advantage over those of us using the controller the game was designed for. This was a big issue in halo 4, where you could tell who was doing it based on the killcam. I can only assume the issue continues in Halo 5, as I’m aware of players who do it and have told me so.

So basically, is this technically cheating? If not, why not? It should be and I really think something needs to be done about it. I was reporting people doing it in Halo 4 through XBL, but as there are no killcams in Halo 5 I can’t be sure who’s doing it. Surely there’s some way to stop this?

There is see who’s in the by the one next to the menu button the other side then hilight the one your after there done :).

Kill cams were very broken in Halo 4 OP, so what you were seeing was a combination of that and lag. There wasn’t really any cheating until very late on in the game.
