"Low ready" stance is a real life stance used mostly when going in unsafe zones but when you are not in inmediate danger, its a stance between walking with your weapon up and holstering your weapon or using tactical walk.
When you just run in the game by default, your weapon is in a low-ready stance, but i want to suggest to add low-ready stance as an alternative for putting your weapon down.
This would be useful for CQB as the low-ready stance needs less space than holding your weapon up, besides, if the devs could add (or anybody can script) a feature for the players to get worse aim when having your gun up and crouching or standing up (Simulating arm strenght stress) this would be useful.
