I really don't know about it making the game sweaty, I remember back when I was 12 or 13 years old back in CSGO days where learning the spray pattern was something cool to learn to be better at the game. However, we are so used to the randomness by now that would make it hella weird even for the pro players to be changing the way they shoot cause implementing spray control patterns = the shooting style will drastically change and the best precision players might not have a place in an environment where its just spray control
