A void subclass for the Hunter. I'd call it [i]Deceiver[/i]. Super: [b]Decoy[/b] - You briefly go invisible and send out a hologram decoy of your Guardian that distracts enemies. This would really only be useful in PVE
Alternatively: Super: [b]Play Dead[/b] - For a limited time, being struck or shot at causes you to fake your death and go invisible. This could be useful in PVE, but I see it being used more in PVP. The first one kinda reminds me of Halo: Reach and the second sort of reminds me of TF2.
