694 is very happy about choosing not to go under the low bar. We originally intended to try for low bar, but we quickly abandoned that idea during our CAD marathon when we realized that our design just wouldn't fit.
We knew from the get-go that having a low-bar capable robot is an absolute necessity for eliminations, but we didn't realize quite how ubiquitous low bar capability would be. By building a tall robot with a really fast drivetrain, we were able to breach extremely consistently. If you forget about South Florida regional (which we so dearly wish to forget), we were able to breach every match that our robot was working (and some matches that it wasn't).
We also realize, however, that we are the outlier in our success, particularly in that we were a #8 seed alliance on Einstein. Being able to go under the low-bar and score low goals is huge in qualifications, as it opens the door for captures much more frequently than would otherwise be possible. Seeding first is also hugely valuable towards winning events.
TLDR:
The ubiquity of low bar robots made it easy to get the advantages of low-bar for both qualifications and eliminations. In a world where low bar was more rare, low bar robots would completely dominate because having at least one low-bar bot is basically mandatory for a strong alliance.
