Summoner Spell Clairvoyance Rework/Change

I'm your regular LOL player, and I want to discuss in a formal manner about the very unused/nonmeta summoner spell Clairvoyance. I wanted to talk about some ways why it can be viable and why it isn't in the meta.

Why it isn't in the meta? Probably because wards and vision in game are way better. Also feral flare's ward range is way more useful and way more effective. A ward that lasts way longer, and won't get you in danger.

Changes to make it better/viable. We can allow Clairvoyance to have a VERY low cooldown, this will allow players to find if enemies are near baron or dragon without having to be there.

Let Clairvoyance's vision slow enemies, and give vision. This may sound quite funky, I know but it is quite an interesting concept. We can use clairvoyance for offensive and defensive uses. This will allow some counterplay.

Counterplay Spell - Blindness All enemies will have no vision, including with wards and spells. This will also cancel all spells during this period that give vision, aka Clairvoyance.
