New game mode for Harrowing 2015 (You guys can come up with a name)

Just a little thought I had. I thought to really capture the spirit of the harrowing, we could have a game mode on summoner's rift but very dark and that you are on your own and you fight everyone else with a very large (almost ascensioned like) nocturne looming around and can teleport in random places across the map and can ult whenever he sees you, but he could have a range indicator of his vision or something idk. Each player is spread evenly throughout the map in random places. and there are health and mana shrines as you cannot recall/go back to the fountain. there could also be a thing were there are gold pads, when you step on one you get a sum of gold and you can buy things from the shop, these pads will restock with even more money depending on how long the game has gone on for. This was just a small thought I had and obviously this could be expanded into something greater! Additional ideas are massively appreciated! :D
