I don't know if this is working as intended or a bug, but since either the most recent patch or the hotfix, the laser attachments on my nyx are on when i die and see my dead body, even though I had it turned off. I've been doing terrible the past few days too, enemies are spotting me almost instantly. I suspect it is because of the laser always being on, is anyone else noticing this? I was under the impression you could just turn it off and no one could see it but you'd still get the advantage. If this is no longer the case then I won't be using laser anymore
Someone said awhile back that turning off the laser dot only removes it visually from you, not from the enemies. I don't own one myself, so i can't check personally.
