And what is the weakest link?We love Bricks.
Bricks is a great example of why the dive op cheerleading drives me nuts. Not every dm knows how, (or just doesn't), dive Bricks like it should be dove.
A chain is only as strong as its weakest link.
When you do a dive on a site with the potential for complicated maneuvering, part of the DM's job is to estimate the skills of the dive group and decide what they are capable of doing. You can do the same dive site with the same DM on two different days and have two different dives. If someone in your group has poor buoyancy skills, it can have a big impact.
