How to make Support more FUN!

I noticed that in basketball games I actually enjoy playing the point guard role and assisting my teammates. (Basically supporting them) While they score most of the points, however in LOL I have no interest in playing that role, and I feel like the thing that separates normal supports (Not mages obviously) from that is their inability to make mechanically rewarding plays, (This Lee Sin of Bot lane aside) There's a reason why Thresh is the most popular support, he just rewards good players more than other supports. Janna just stands back and shields the adc, her best mechanic is aiming her tornado. I think Ali is cool just not meta atm. Leona is so easy even a caveman could do her job. Raka is a joke lol. Sona only has her ult stun to make plays, which is honestly a pretty bad ult. I think every support needs atleast one skill that is both game changing and mechanically rewarding to be fun to play.

Thresh would be the best champion to draw from, he is a very mechanical support, Alistar too if he was meta. Leona is just too easy to play, you make plays but nothing separates a 20 game Leona from a 200 game one. And Soraka, Sona, and Janna all lack something game-changing, though Janna and Sona are close atleast compared to Soraka who needs a full on rework lol. Sona's ult is kind of game changing but its just not as good as other ults, I say make it harder to hit, but reward hitting it more. Janna's tornados are interesting, but not dynamic it would be cool if she could call her tornado back, sucking in teammates so she could then ult and heal them lol, maybe something less OP but still something dynamic. Soraka is just a boring champion, I like the silence zone she can create its the only skill in her kit, maybe expand on that more. To be honest, she heals enough I'd rather her ult be something that's not just more fucking healing!
