On summoner rift map

I think it would be cool to take a crystal scare aspect and add it into summoner rift map on the dragon and baron pit's and a crystal node to each side of the pit, 1 crystal for each team, and what they do is act like a ward but give vision of the whole pit for 3 mins when they are activated by their respective side, and they are activated like you would in crystal scare u channel it for 10 sec then it lights up, just rough idea, can be tweaked or changed, i still think it would add.change the way baron and dragon are warded/controled.{{summoner:17}}
