Supports would love this. The spell would be used a lot more and it would really add a little more safety to bot laners without escapes. Maybe make it an aoe? Edit: supposed to be "make cleanse a targeted spell"
Edit2: Barrier could also have the same application
Interesting idea. I support it.
Agreed. I want more diversity for summoner spells than just ignite and exhaust for support
Wouldn't that lead to making it mandatory on all supports?
I feel that it wouldn't be a very fun spell because it would feel like the support is effectively "giving away" their second summoner spell slot to their ADC.
Yes, usually the support takes a spell to help the other player (usually exhaust), but it's still "their" active spell which they can use to make plays in a variety of situations, as supposed to this targetted-cleanse which would mostly just be a reactive spell to use on their ally.
Supports would love this.
is universally solid and supports can already grab 
.It's also worth noting most marksman just don't have anything worth cleansing, and a lot of supports deliver types of CC or sudo CC that cannot be cleansed, as cleanse doesn't do anything vs. pulls, knockbacks, knockups, slowing fields, blinding fields, or suppression.
So: 100% useless vs. 
.
Well - you can cleanse the 0.5 second Blitzcrank Silence, but really. That does not make Cleanse worth it, he can use that every 30 seconds compared to 3 minutes.
Even when gets mega-CC potential in 
; 
is still 100% useless vs. him.
Also: biggest threat you're usually trying to save a squishy from as a support is an assassin, and assassins usually have the weakest CC in the game. While you could technically remove the fraction-of-a-second slow Talon applies and reduce his damages by 10% with perfect timing (oh man), no assassin is reliant on CC enough that Exhaust isn't simply better. Also worth noting Cleanse vs QSS/Crucible/Scimitar differs in effectiveness in that Cleanse cannot remove non-CC debuffs and it cannot remove Suppression, while the items can remove a wide range of non-CC debuffs as well as suppression.
This in effect makes Cleanse a poor summoner vs. the mark effects applied by
, while the cleanse items can at least remove those marks.
In which case: 
exist.
Also: biggest issue I have with cleanse ATM is the (lack) of QoL features it has. Mikeal's has a projectile that's fairly slow and unresponsive, leading to a lot of frustrating scenarios using it's active: especially seeing as the difference between 1 frame can mean a 0% CC duration effect and instant-cleanse or 100% CC duration from blowing the effect a fraction of a second to early. Cleansing a CC duration that's been in effect for 70% of it's total time is also fairly useless and a sub-optimal way to spend a 3 minute CD.
Yes to cleanse...
HELL NO to barrier...This exists in HOTS and is cancer.
