New Game Mode idea: Daaarkness

I'm pretty sure this was suggested before, but what the hell i'll suggest it again.

Basic gist: No shared vision. You only see around your champ and around any wards you place, but everyone and everything else is hidden in the fog of war (wards do not give vision for your team, only you).

I was thinking though that there would be some small objectives your team can get similar to scuttle crab that would give team vision. Perhaps the jungle camps could be changed a bit to give team vision in the area (and taking enemy jungle camps could provide you with vision of their jungle in that area, and simultaneously take it away from the enemy team). Maybe this could be done in the form of little glowing fireflies in nearby brushes or something?

So the games don't take forever due to coordination difficulties resulting from no shared vision, I think it'd be good to have increased gold and experience gains throughout the game.

I think finding some way to gain some kind of shared vision would make for a fun objective in this game mode, but I'm unsure how it should be done for the funnest effect. What do you guys think? Would you play a game mode like this?

EDIT: As for which map this would be played on, I imagined it on Summoner's Rift, but I suppose it could possibly work better on other maps. Which would you think would fit this best?
