Why did they discontinue to use figures in figure skating? Back when, the skaters were tested for balance,footwork, overall coordination and basic skills also acrobatic flair.

Why didn't they keep the compulsory or "school" figures? That's the part of figure skating I miss. I though that part of the figure skating was beautiful to watch. The way the skaters formed the tangent circles with instructions as to which edge of the blade and which foot to use in tracing them. When the skater performed their three figures and the accuracy of the tracings, cleanness of the lines, and graceful carriage of the skater were important considerations in scoring.

Can any body remember what this meant in the figures:
