Looking for some good advice.

Simple enough concept. Before the next season starts I've been steadily working my mechanics, even including outside sources (friends mostly) to help me work on some things I know I've been lacking. But I know there's more I can do, and so I'm basically crowd-sourcing.

What are things you could help me out with? Any information is helpful, criticism, theories, even repeated information has relevance. I can give you any info you'd like to have pertaining to my game play, I'll even get into a game if you feel the need. I have nothing but time on my hands and I have the motivation. The only thing I lack is scope. I like to have a good solid view of things to work on, and unfortunately that knowledge isn't just given to everyone equally.

Also, if you'd like pointers or advice from someone at my level (plat 2 currently) feel free to ask.
