Looking to gain experience through more coordinated team play but also trying to make sure everyone has fun

I mainly play as a sova main and IGL in certain areas of the game, otherwise I can fill based off of preference. The highest I hit and maintained was Immortal 1-3 across 4 accounts back in Episode 1 and mainly played 10 mans/scrims over ranked due to the coin flip possibilities which is why I hover between plat and diamond since I don't play ranked often.

I'm a very supportive teammate and while I come in with the mindset of winning, I don't allow toxicity to come in order to keep myself disciplined. I'm learning to learn new roles if needed, create strats, alter playstyles but prefer to be a sova main across all maps except split (switch between sage and cypher based off of team comp.

I'm a full time Uni student so I'm trying to play more as a sub player rather than a starter (unless needed based off roles and other circumstances).
