Support gold income idea

So, supports just don't get gold, we all know that. A big part of it is that they have to buy a support item AND sightstone, or combine them, but sacrifice active item effects. Why not give sightstone increased gold per second based upon map coverage across the team? It would be a neutral power spike for pro play, and would give more incentive for layers to ward in lower elo games. Also, supports are boring to many people because they aren't super flashy. Of anyone remembers when thresh was released, support was one of the more popular roles back then because he brought just so much playmaking potential to the role. I know that many people picked up the role when he was released, and bard is the only other champion I can think of who revolutionized the role as much as thresh. Lastly, if more lanes were opened up to support, as was done with ivern(though he has not revolutionized the role much yet), more people would play them. Imagine a support who could legitimately go top lane, while there is a bruiser bot who can legitimately fulfill his role. Champions don't have to be released in an op state anymore, and if a champion is severely underplayed on release, support them by making other champions work well with them.
