IMHO, each team should pick the defense that they are best capable of handling, and do it twice. "Best" being an alliance wide decision. For example, Portcullis may be at the bottom of your list, but you may be the only robot in the alliance that can do it.

1) Assign the first 3 defenses that way.
2) Of the remaining 2, pick the one that the alliance likes best, and any team (after they defeated their assigned defense) goes after that one until it is defeated.
3) If any of the top 3 are still undefeated, go after that one.
4) Then go after defense #5

Exception: If your bot is the only one in your alliance that can defeat Defense #5, AND things are going swimmingly, then your bot can skip 2 and 3, and go to 5. In essence, you are trusting your team (after they have proven themselves, and things are going swimmingly) to finish defeating the first 4 defenses, and you spend your time with the one they can't do.

Note: The best shooting robot that is also fast and can easily pick up Boulders should be assigned the quickest defense. Their job will be to score shooting points while the other two are busy crossing defenses.
