On the subject of upgrade options for Sightstone, I think it should follow a slightly different set of points:
 * If you want different upgrade options, each Sightstone upgrade needs to somehow cater specifically to the playstyle of each champion type who usually builds this item. Since this almost completely overlaps with supports, bar certain champions like and, it would work best as a trifecta in the same vein as ToA/FQC/FotM. Lee Sin and Jax, being either naturally tanky or transitioning to tanks, would do best with the fighter/tanky-support upgrade.
 * Currently Ruby Sightstone has no flavor. It's quite possibly the most pathetic upgrade option in the game, offering no additional bonuses or interesting effects. It just adds 250 health and holds one extra ward, which is irrelevant in Season 4 owing to the ward cap. Each Sightstone upgrade needs to offer some kind of unique bonus that would cater to the brand of support it's designed for.
 * That said, vision itself is used in the same way for all supports, and should be the same across all upgrade options. This means that, although you can reward people for laying wards with role-specific bonuses, you can't add an effect to the wards themselves, particularly as they're meant to be used outside of combat.
