Hey.
On phone, so can't give you specifics.
There is two Discord servers I think. Think Tank and the one I'm in. Not sure what the one I'm in is actually called.
There's a lot of well written guides to help you understand the aspects of this game. Most important is adjust your player weights to match the game engine we're on (4.5). The default ratings are mostly useless if you want to be competitive. I'm using a slightly changed version of setherick's weights. I'm sure you'll be able to find them in a sticky somewhere.
Regarding gameplanning and selecting plays, there's also guides for that. I can't remember the name, but the 3rd category in community forum I think there's a post with pinned messages that should help you.
I'll get back to you when I get home if nobody else has answerred. :)
