Riot says they don't want Sightstone to be an item supports need? Here's an idea on how to fix it.
We already have the technology to scope out which characters went into which lane and how well they did, so why not, by the 8-10 minute mark, take note of which characters went into which lane, what their item picks look like, and what kind of CS they have, and then give them a "secondary"-type trinket that functions exactly like Sightstone does?
