I am a support main. I used to go Heal/Clarity with Sona and poke a lot. Now I got runes and know better to save mana so I replaced that with Flash but I think Clairvoyance is a really useful that can be good to look at baron or dragon or anywhere else in jungle areas. It can also be good to see if a missing enemy missing for a long time is afk or not by looking at enemy base. I'm thinking of using that spell. I use Soraka a lot and since most of the time my adc takes heal instead of barrier an I take heal too, it might not work as well. So should I replace heal with clairvoyance for Soraka? Or is there any other supports out there which Clairvoyance can be a good spell to use on?
in my opinion, clairvoyance isn't very useful as a summoner spell anymore because every player runs some kind of combat summoner's spell now (or smite if you're the jungler). Clairvoyance used to be a meta summoner spell back in season 1 but over the years, players have gotten better about warding. Besides, if you really wanted to use clairvoyance, you could substitute it with the blue trinket which does essentially does the same thing.
You should replace heal with exhaust. Exhaust is a very good summoner spell to help protect your ADC and is extremely important against assassins/high burst mages to reduce their dmg. Taking clairvoyance will not save you in a life or death situation where the enemy is charging at you or your allies.
