Well, while I Zyra/Morgana mage supports, I really just play Enchanters, specifically Nami and Janna.
I have a strong preference for high damage ADCs or sustain damage, with my favorites being Draven, and Vayne, but now I lean more towards Kai'sa than Vayne. ADCs that can supply their own CC, such as Caitlyn with her traps, or Jhin with his own traps, are nice, but I find they rarely if ever actually use their own CC, making lane a bit more difficult than needed.
I don't know why, but I despise Ezreal ADCs, they've just always rubbed me the wrong way, and in regards to gameplay, I always found him a bit lacking. Sure, he's hyper mobile and hard to pin down, with decent poke in lane, but late game, in my opinion, he falls off hard, and doesn't deal nearly as much damage as any other ADC could. That and I rarely if ever see any good Ezreals, most just pick him up because they're new, or like his whole "boyish adventurer" thematic. I also have an unending hatred for Sivir, she's just lacking in every department when compared to other ADCs. She has decent enough mobility, but her damage is lackluster, she lacks any CC, and she can only stay in fights for like 3 seconds before she runs out of mana.
In regards to more off meta ADCs, I've always loved Yasuo ADC. His windwall is so easy to abuse in bot lane, where more often than not you're fighting ranged opponents, and it pairs super well with my Janna, and so I can basically make him unkillable. I also love Graves, and Teemo, or at least, the good ones.
