I definitely think that the most important aspects of the game are:
Scouting
Hanging
If you don't scout right, how will your team do well? By knowing exactly what every other robot can do, its strategy, driving techniques, human player accuracy, things like that, you will do well. Also scouting is key to knowing exactly what strategy to use in a match. Scouting definitely has a positive effect on the results of the matches.
Hanging is also an incredibly important part of the game. I do agree that sometimes the small balls can determine a match, but if your robot can hang really well, then your robot will do great. Unless, you are against a fantastic ball collector. That's where scouting comes back into play.
Scouting is key!
