Agreed. On the up side, when a silly sniper has one attached, you can see them off in the distance, and as a recon, if someone comes up close i use a tact pistol to blind them and kill them, providing i dont get sprayed to death.
What does really annoy me is when team mates look at you without turning it off, or when people are sprinting past you and it keeps blinding you as the gun swings.
