Start putting 
on the support, and have the adc take 
Why?
Because grievous wounds no longer effect healing from outside sources, meaning that should the ADC get ignited, having the heal on another person makes it twice as effective at protecting the carry.
Just a thought.
Illâoi Evê Siôn46 votesFINALLY, I can heal myself when I'm dying for my Marksman, and don't have to hope they'll remember to do it themselves. The amount of Marksmen who never heal for others is terrifying.
GrReaper964 votesAnd i thought i was the only one [zombie-nunu-tears]
blueberrypancake10 votesPersonally I try to heal at the last possible second because of things like ignite or I wanna make sure they are gonna live because using heal on a person that's going to die is useless
morris12 votesFor some reason I see most marksmen do the opposite and heal me when I'm caught out by Blitz hook, even though I'm level 6 
and have over half health. Then again, it shows they have a soul so yeah :P
LankPants39 votesIt's also worth noting that a lot of supports will run Windspeaker's, making the heal stronger and granting resists to the carry when they do pop it.
therealdragon10 votesThis would work....but it'd help if heal actually did its job.
Like legit, I was a midlane brand, roamed bot and killed their supp and adc was gonna die soon. Someone dived stupidly (normals, mistakes happen) and came back just barely surviving with a few minion attacks that would surely kill him. I actually remember I have heal and press it but then Galio dies.
Let's forget the 10 health Galio who's literally 1ft from me. No lets heal the full health quinn thats 10ft away -_-. Like srsly?

Ok turns out I was slightly wrong, Galio didn't die straight away, but had heal worked he would've survived the encounter against rengar
edit2: k turns out I was even more wrong. Apparently, my cursor must've been near quinn moreso than galio :/.
Azure Dancer1 votesIt heals the person closest to your cursor I believe.
Baron of Bread13 votesIf you didn't have your cursor over Quinn then it would have gone for Galio. It targets the lowest health ally only if the cursor is not over another valid target.

It heals the person closest to your cursor if you didn't know
The Loveless1 votesTo be fair, Rengar would have killed him even if he received the heal. Don't beat yourself up too much, buddy.
RedCyclone6 votesFuck that I main Sona and I run Ignizzle and I sure as fuck for shizzle the enemy laner and end on 10+ kills
"SUPPORT"
TendajiX1 votesThis made my day omg XD
Stars Shaper4 votesNice to know, that totally skipped my eyes and brain.
Plus it gives ADC a way to keep under check their enemies without the need of a support.
HenryDahNewb4 votesFor me its on supports and 
on adcs for the old fashioned protect the doublelift comp.
Penns3 votesGrievous wounds are only 40% healing reduction now tho, so its not twice as effective.

SirNewton123 votesWhenever I have to support I go Zilean and I take and 
because I have a gigantic slow already xD
High52 votesIf I had a nickle for every time I played Naut and someone asked me to take exhaust ... :(
Rıots Bad Client2 votesYou, whaa... You take for the slow, I take it for... everything else.
The slow is just a minor bonus. :B
The Loveless1 votesYeah but Zil's slow is so huge that people can't orb walk, kite or escape. They have to essentially crawl and deal with your minion wave and/or a gank and/or an engage from just your bot lane.
Zavern2 votesYou are aware that exhaust reduces their damage by 40% and protections by 10 right?
ModWulf Helhammer2 votesI can see that working, but only if the support is with you 100% of the time, which they aren't. Heal is also used for more then just healing, the MS boost can be used as a quick escape, or last hit on a champion
GrReaper967 votes
anyone?
SH Azykan2 votesThis is..actually really smart. Paired with the one keystone it also makes the heal even better for the support to have...huh Well only if the support is one who can run that mastery, otherwise it might still be better for the adc to carry heal and the support to take exhaust/ignite
Lunar Silkworm2 votesI took exhaust on my ADCs 90% of the time even before the season change, especially in ranked.
Reducing incoming damage from an enemy diving champion by 35% is more effective health than what heal's active gives to you, it improves your dueling against other ADCs (I've outdueled an enemy Vayne due to exhaust alone), and an ADC is most able to make full use of its reduced armor duration.
The only ADC that benefits more from heal than exhaust that I can think of would be potentially Ashe, and that's because she has natural kite and range to work with.
FistOfSharkiesha2 votesI disagree. I've never believed in the concept that the support is some martyr that has to die for their adc at every moment. The ADC needs to be able to have control of the MS boost from heal. Most supports have some means of escape (slow, MS boost, stun, shield), but very few ADCs are safe. If the ADC is ever caught out without the support, they need that MS boost to get away safely.
FastAsHeck2 votesor just run 2x this spell is way too underrated
Daedalus8711 votesI'd much rather run cleanse or ghost on my ADC than heal, and you sort of need an exhaust for when that one person on the enemy team gets ridiculously fed.
So while this may be appropriate in teams, I wouldn't do it in solo queue.
Der Lindwurm1 votesPeople seriously LOSE THEIR SHIT when I take heal (or anything other than exhaust) as support, though.
blueberrypancake2 votesIt depends on the enemy comp but I'm ok with the support taking ignite
My Waifu Vanilla2 votesI prefer my supports to take ignite over exh anyway especially with all the lifesteal going around and its easier to get a kill in lane with it.
7Artemis71 votesI like taking ignite on supports with high kill pressure (
, 
, etc.) but I usually ask the ADC first because if I don't ask they rage.
IceKingChernobog1 votesthis is interesting
Ipols1 votesI used to ask my ADC to switch exhaust for heal not for the OP's reason, but because since Zed and Talon keep going for him, he can exhaust them faster in case I'm engaging or doing other stuff
Primaquarius1 votesI take / all day regardless of role, because its just so effective for 1v1 or escapes
The Loveless2 votesI love getting a killing spree from people who don't run flash. Bless your kind soul.
Primaquarius1 votesThe downvotes tho...bless these meta sheep and their inability to use other strats
The Loveless1 votesI mean it's not that your setup is bad in a 1v1, it's just bad because you can't push out. You are constant gank-bait, and once you use both heal and exhaust, you're a quick meal in a 1v1 against whoever your lane opponent is, because they probably have a level and item advantage after repeatedly killing.
I have never lost to someone who skips flash, even if it's TP top.
Primaquarius1 votesIf I'm low health, my strats in a 1v1 just involve more distance
God of Anime1 voteslooks good on paper only. heal is still essential on adc
The Loveless1 votesRight, essential. And before that it was cleanse, and before that it was barrier, and before that it was ignite.
Strats, son.
Hyrum Graff1 votesI always loved doing that as Soraka support, so I can heal myself for even more heals for my adc ;)
The only issue, honestly, is that everyone is so used to playing with heal that they forget how to use exhaust :S
God of Anime1 votesso hows the exhaust adc meta going for you guys?
