Do You Watch Re-Runs Of Your Matches In Theater?

Just wondering if anyone actually re-watches their matches from theater mode.
Like do you save the one’s you do really good on and the one’s you do really bad on.

Is there any benefit from doing this other then it being a waste of time? Do you learn what you did right and wrong? Do you seem to notice patterns that “casual” players go by? ect ect

Also do you play better if you’re in a group that uses teamwork and do you win more then playing alone? I’m tired of loosing more then winning. Victory is all that matters to me.
