Personally I'd say for supports it would be Janna
A lot of Janna players still play her as a backline sheild support and take summon arey+resolve. Because of this it makes a arcane commet+cheap shot build super inflated stat-wise.
Other than that, nami is pretty easy, and I got an S+ the first time I ever played morgana.
Champs with higher playrates are generally easier to S on since more bad people play them lower the bar to get higher ratings
Katarina support .......as not many people play katarina support. kinda a joke but also kinda not.
Theres two easy ways of getting s ranks, either play a champ good in a role their never played or play a popular champion whose criteria would be dragged down by shitty players.
######also DH on poroking, as for some reason the nerf from aram didnt carry over.
Fat waveclear champs. Personally I can achieve consistent S rank on Tryndamere, Katarina, and Annie simply because I've played them a lot AND more importantly I get a lot of cs in my games.
Azir.
I genuinely went 2/2/3 on that champion and got an S because I had 9 or 10 farm a minute. So many people feed on him that just doing okay with great farm is enough for an s.
Just play any champion in a off role and don't suck. Easy S right there.
afk farm in jungle.
you can go 1000/0 but if your cs is bad, you get an A+.
just farm in jungle 24/7 never stop. go 0 0 0 doesnt matter. you will get that s
In general I would say it is really easy to get an S grade on basically every enchanter champion.
I have absolutely no clue how to play Karma, yet I was able to easily pull off an S by simple staying behind avoiding death in laning phase, then spamming my shield on the most fed guy on my team in mid game. You get tons of assists by them being fed while staying completely out of danger yourself. Same applies to Janna, Bard, Lulu.... you can do this on any support who either has a shield or heal in their kit to spam on your carry.
