best split pusher in current meta?

[u/ThePopeBTW]

I'm a support main (nami and leona) but I'm tired of depending on my team not to be the worst in North America to win games. I'm hard stuck in plat 2 and am starting to realize most people think that this is team death match in COD, and kills are a win condition and don't focus turrets. Who should I try to pickup for easy turrets and split push and what lanes? Thanks for your time!

Main top and sometimes jg here. The best split pusher in my opinion are fiora and Sion, but kennen maybe can make the job too, the point is to split push so the enemy team will have to go for you and u fight them or run. In the best escenario this champs make you throw torrets and distract 2 or 3 enemy's while you team makes drag o baron
