I’d like to learn from a higher elo player anything that will help me improve. It would be great if they have experience with one of my favorite chamions.

Currently I am in Silver.
Have played 90% Jungle, on and off since 2012 or so.

Mains:
Nocturne
Master Yi
Warwick
Nasus
Shaco
Udyr

I want to emphasize my mechanics and the choices I make (plays), as well as team fights. That seems to be where I lose most. Open to all insights though.
