Think it needs a Rank V version that goes up to level 60 an below mobs, obtained at level 48 but very nice for the DoL,
(Though i don't know how often players need to look around the areas with L50+ mobs for gathering locations, so i could be totally wrong with that. )

But Great idea, and lol, making people walk, But I have to agree with Sephr, I'm hoping for some visual effect, just not us looking transparent please, dark smoky effect over the character maybe?
