Your stats and win% are very good. The only thing I'd say is keep shooting for 10cs/min!

Also, add me if you wanna duo with a solid Jungle!

Yo' high plat support main here, so a limit on what I can offer, Take it with a grain of salt

1.) Your overall scores are quite good, but its pretty limited, normally the first piece of advice i offer is work on dying less, but your KDA and scores are quite good, so keep doing what your doing - play more games and you'll see yourself climb.

2.) You play a very wide range of champions and roles - That's fine, but i'd work on focusing on a single role or champion to 'main'. As you work your way into high plat, I found its better to be focused on one thing and do it exceedingly well. Jack of all trades can help, but make sure you got your mains down. Score-wise, your seem to be VERY good with Xayah. She's very powerful in the current meta as well. (currently my go-to ban in ranked play.)

3.) Work on closing out games and understanding late game power curves. You seem to have laning down pretty well and you seem to handle teamfights well based on your scores, so look at scaling and power curves next. Which champions are terrifying come late game? Which team comp wins late game? Questions like these.

I'm Silver 3 so i can't offer much advice but try playing ranked late at night on week-ends. Usually i see a lot of serious players play late at night. Might be just me though.
