Medium-high mechanic champions, help me get a complete list please.

I have been a Tryndamere and Heimerdinger main for long enough to know that medium-low mechanic champions are not how I, personally, can carry. I cannot even with full focus and efficiency carry a team with them. This realization led me to try out Fiora and Yasuo to which I found extreme natural talent that I literally didn't know I had. On the other hand, when I tried to master Katarina, Riven and Zed I found that it was too much thinking to the raw mechanics so that I couldn't focus on farm and DPS without being scared of making one wrong move.

I would say my skillcap is at precisely a Fiora, Yasuo, LeeSin level. Champions where the abilities aren't nonstop spam but close enough to it to make them OP if you master them to a high enough degree to 'carry'. As far as ADCs go, I'm trying to work on my Lucian and, when I can buy them, I'll look into Jhin and Caitlyn as I realized Vayne and Tristana are too reliant on their team's mechanics for my brain to have natural talent with their style of carrying (I know Vayne is considered high mechanic but for me she feels the opposite, I focus her w and three-hitting in trades and it feels so empty in overall impact). Kalista and Sivir feel too hard to 'think ahead' for me to utilize the true capacity of their potential (they are like the Katarina and Zed of ADC for me).

So basically, I'm asking for champions that you guys judge as of the level/range in mechanics of Lucian, Yasuo, Leesin, Fiora and...

Thanks for your help in advance. I will truly read every post and consider what you have to say, I am looking to master Evelynn next, I feel she's a leesin-level mechanics of Jungler but don't have the IP for her (no point using RP since I'm enjoying mastering just those champs for now on unranked anyways).
