From what I saw at the Suffield Shakedown:

Crossing a defense in Autonomous is a must do for the 10 points.
Spybot scoring could be worth the same, but if you can do that, why not work on crossing a defense too for 20 points total.

The high goal may only be worth it in autonomous, after that, the 3 point gamble of missing a shot against a defense (with a better view of the action) and extending your cycle times cuts into your ability to capture the tower and get the Ranking points or 25 in the Playoffs.
A sweeper Robot could help to weaken a tower quickly.

Breaching 4/5 defenses is a good idea for the Ranking points or 20 in the Playoffs.

An actual match seemed pretty quick, given the number of tasks that are possible time vampires. I think you’ll be lucky to get in 4 cycles and capture, let alone scale.

Scoring in the low goal seemed trickier than expected with the sloped batter. A good strategy may be to shoot it up the batter with enough speed and proper aim. Positioning and aiming is difficult across the field, that’s where a camera on the Robot can help.
Like the balls in Rebound Rumble, boulder characteristics will change. Many get crushed under Robots on the floor and some defenses.

The Drawbridge may be a very popular choice this year as it blocks the drive teams' vision, but that cuts both ways. Nobody manipulated the drawbridge or sally port from the neutral zone today, but that may change. The ramparts and cheval de frise take time and are difficult.

Some Robots died on the Outer Works. Make sure your connections are tight and sturdy.
Robots that get stuck on a defense can be freed by an alliance partner.

I am sure this will change, but I think that an effective alliance will have one Robot dedicated to breaching, and two Robots dedicated to weakening the tower.
The breaching Robot could hold open the drawbridge or sally port, while the scoring robots cross them from the neutral zone to score.
You've got to outscore the opposing alliance to get your precious Ranking Points.
In the Playoffs, teams may gamble on a defensive Robot, at the expense of possibly not capturing a tower. But if you've weakened the tower by 3 or four in autonomous, that may not be an issue. Then again, if by the CMP the towers start at 12........ Oh dear, I'm headed down the rabbit hole.

Can't wait to see how Stronghold is played by week 5.
