@Matt_Allen the visualizer can be used on immediately sniped victims on any map to track down and kill the traitor. If the D is quick enough, you can even kill the guy if he's still in the exact same spot. Can also be used to kill on last seen in certain scenarios, such as if the dead innocent is staring directly at the guy who shot him. To be proven by the visualizer, as well. EDIT: If I'm wrong, please remove this post.
I think if this does get added, it would be all the more reason to add the traitor weapon of the gas can that @nickmain1999 suggested.
That was actually part of why I suggested the gas can, I was hoping that both would be implemented making a cool combination.
My thoughts are here: Spoiler -1 unless making the smoke grenade into this weapon I'd also rather have a Jack Hammer than this
