We mostly agree. Points of contention, since agreeing with 90% of what you said would take forever, are:
1) As everyone above me said, floor pickup is more important than it seems. Let us not forget the lesson of Lunacy. If you miss, or if your opponent drops something, and you can't pick it up, you have an inherent disadvantage. Alliances need at least one member who can pick up tubes from the ground or the opposing alliances will just throw all the tubes halfway across the field and take them home.
2) Our team feels that around, not through, is the superior option. For one, it isn't specified that a team on defense that gets pushed into your zone has to leave, ever. For two, going around can be just as quick as going through with a good driver, because you don't have to worry about the other team pushing back. For three, we already had a solid mecanum drive built from last year and our decision saved resources.
3) I'd argue that defense has a role to play. It's better to play defense on your opponent who has a tube that could complete a high goal than to, say, try to score on the low goals. Plus playing defense gets you closer to your towers for deployment.
