New game mode idea

So a while back i remember someone talking about this and i wanted to bring it up. It was a special game mode where 1 guy who was an assassin and had to kill the 9 other players on the rift. He had full map vision and everyone else had limited vision and had to kill him before he killed all of them. I liked the idea a lot and wanted to play it but it never came into flourish-on. Granted the idea may have some kinks when it comes to gettign gold but i feel like that wouldnt be very difficult to solve. But if you guys have any comments on the idea id like to hear them.
