Support main* here - I see little value in going to tier 3 support items

With the exception of on the tank supports granting 10% cdr and a decent health boost from the gold and item slot investment, the final upgrade is an absolute last purchase, if ever a purchase at all before selling off the item for any utility item or even a deathcap.

-> is 10 AP and some irrelevant amount of health for the characters that buy it for 600g

-> is just a paltry amount of health and regen useful exclusively for a Soraka with , again for 600g.

An extra ward doesn't make up the difference in price at all. When these items were built out of sightstone it wasn't for the value they offered as a gold purchase, but rather as a means of optimizing the efficiency of supports' item slots.

With sightstone removed, the upgrade feels like a complete waste of gold since the support items give wards and useful stats on their own already.

and Ruby sightstone offered options in echange for item slot use, giving the four wards and more frequent ghosts tracking, same with and Ruby!ss. As is, there's just better use of 600 gold at any point. That's a boot upgrade, or a finished or just 50 gold off from , or hell, just spending an item slot to get 25 extra AP for an enchanter's spells.

*Actually, top main four times over any other character in any other role, but I play a wider range of supports more often overall.
