What a load of shit. I just realized now that I've run into other players using this. Halo 5 has amazing replay features and when I get absolutely demolished by someone I like going back and checking out what that person was doing. I was amazed by what I saw sometimes because I could swear it looked like the players who were absolutely dominating everyone else were moving like a mouse/keyboard player. I didn't really think too much about it and just chalked it down to me being old and not as quick as I once was but having read about this thing I'm starting to have a different opinion now.
What's worse is ppl using it on PC for blops3 and trick the game into thinking they are using a controller. So they have aim assist enabled like the controller morons...
