Why not left handed weapons or charecters ???

A lot of games like CS2 , VALORANT, even COD MOBILE have adopted the southpaw grip on the gun , it actually is realistic because a lot of players feelcomfortable when viewing guns held on left hand or a lot of lefties would find it more immersive, at some point this is going to be in every game ultimate down the line soon because many games wanna beat their competitor with even the slightest edge , this is somehow undermined by both COD and Battlefield5, let's see who does it first !!
