Enchanters are quite good, especially because the meta adcs like Kogmaw, Vayne are very strong and benefit having lulu especially, which makes her S+ this patch.
Zilean is also quite a bit better
brand is better overall, so he is buffed in support too, he is better version of zyra now.
Zyra down a tier, she is very good vs melee comps ( similar to brand ) but now brand is just a better zyra except if you really want to peel, but if you want to peel why play mage supports.
Taliyah support down a tier, the rework makes her worse at being a support, her roams are worse, her early game dmg is worse, burst is worse.
Jannas winrate is very high, but IMO she is worse now than before because she was very good dealing with melees diving in and stuff like leona rell etc in botlane, compared to other enchanters, now its more enchanter vs enchanter and the one that scales the most wins, janna isnt sona level lategame, nor does she have same synergy like lulu with vayne kog etc.
renata is S+ vs melee comps, S/A+ in normal games
Pyke lost his gold, but he is still strong in lane and hook champs are best to defeat the enchanters.
melee supports = alot worse unless its extremely good lane matchup.
