As a Support Main - A HARD HELL NO
Riot, I get that you want to balance the game, I really do. But removing the tier 3 support items in lieu of making everything a Sightstone is not how to do it.
Simply put, Sightstone is not satisfying. It never was and it never will be.
Therefore, making me as a Taric main give up the hella good shield for myself and that incredible clutch shield for my allies to basically always make Eye of the Mountain feels like complete and utter dogshit. Face of the Mountain is a satisfying item. You felt like you achieved something by finishing the quest, and the active is so beneficial for many supports and their ADCs. It was a mini "oh shit" button that was one of the very few shields that was never abused. Removing such a satisfying item is just utter garbage, and I hate it. I wanted to have the extra shielding as a tank support, and no amount of Knights Vows or Zeke's Harbingers will have the satisfying thud that Face of the Mountain has.
This same holds true for Frost Queen's Claim and Talisman of Ascension too, but I was honestly more likely to pick the Eyes over those items in most builds because of the versatility an extra item adds on an enchanter.
My recommendation if you must remove Tier 3 support items - bring ALL of the actives back, not just FQC and ToA. Hell, rework Banner of Command or Ohmwrecker into a version of the live Face of the Mountain. Both of those items are utter garbage anyway, and no one picks them because of literally every other tank that exists. But overall, I think it's a very terrible mistake to remove Tier 3 support items because you want to give out Sightstones. Just make the yellow trinket have an upgrade into a Sightstone if you have a Tier 2 item - make it do a brief reveal of wards near where it's placed when you drop a ward or something so you don't lose the red trinket. Just do anything else other than remove the most satisfying part of support gameplay.

are the 3 main items, which give 750 health, 70 armor, 60 mr, 20% cdr and 200% healthreg. This will continue as the new tier 3 targonitem, currently called "Remnant of the Eternal" on pbe, will ahve the same stats as the eye cause it is a combiantion out of targons brace and a ruby crystal. Farther itemchoices we have:
for Aggresive Tank Supports like 
, 
, 
, 
: 400 health, 30 armor, 100% health reg, ...
for catchers/peel supports like 
, 
: 60 armor,
30mr, ...
for Defensive Tank Supports like 
, 
, 
(Taric), 
(Leona), 
, 
, 
, 
, 
, 
, 
. I believe there are some choices here giving some or a lot of health (warmogs and gargyoels active especialy) and the Zekes user may not get health from that item, but you can split them up to Glory/Redemption as well where they get health.
exists.
while having 60 ad 200 hp and 10% cdr and even then it doesnt account for the saftey and range that those champions have.
Ranged characters are inherently safe phage was made to combat that giving them their own phage but with far more movement speed more than negates that and phage items shouldnt even be a must buy in the first place.
