What did we learn - FIRST Scrimmages?

I saw at least one team at the Rochester Rally deploy a successful winch system and Elevate themselves (378). Team 1507 had a hanging mechanism but I only saw them deploy it once and it was too slow to lift them in the last 20 seconds. A second year team (I think TanX) had a scissor lifting pneumatic lifter, but they couldn't get the angle right and it looked like they didn't have enough air pressure/battery voltage to fully lift themselves.
I saw a lot of mecanum wheeled robots there. If any teams had a high traction drivetrain, I suspect the defense would be quite effective.
Not many robots were operating on the field, so there weren't many opportunities to see defensive strategies.
