Does the hunter call of the wild not support mouse and keyboard if not, that it just ignorant

You have to look at what games support keyboard and mouse. For example, the game I play is called DayZ and it gives yoy the option to join a server with keyboard and mouse so that means you just have to find a game that enables keyboard and mouse. I would
just look up online which games support keyboard and mouse.

Ummm you press far more buttons on a keyboard then a controller thata by design

The ideal of a controller is simple button presses.the idea of a keyboard mouse is quick aiming thats about it

If ark does not support mouse and keyboard i don't see why not it's a pc game too but since it's platforms vary i think I'll have to suggest this on their wild card forums they probably would add it on a future update who knows lols

I'd go mouse and keyboard for monster hunter but controller for the rest.

Mouse and keyboard does not require to be part of the insider program. Just plug a USB keyboard and mouse in.

Rainbow 6 Siege does not support Mouse and Keyboard,

You can use a third party usb device to get a Mouse and Keyboard working but because the game does not support M&Kb, it's classed as cheating and you run the risk of being banned from the game and Xbox.

Games like Call of Duty Modern Warfare / Warzone do have M&Kb support.
