3. Have an escape plan ready when you engage, and be ready for when the enemy turns.
4. Recoup faster, guard faster.
I hope I don't sound like I'm being too harsh, so please tell me if I am, but considering that you are able to create value for your team even with notable mistakes, fixing points 1 and 2 alone probably push you to low Diamond on Aether. You've got this; keep at it.
