Eulers are so ugly 85% of the time! It should receive negative GOE when executed so poorly.I agree with Jontor, ladyjane and others who miss those creative, difficult and entertaining step sequences so many skaters once did. Adding some type of choreographic step sequence to the free skate in singles would be ideal.
If that is not feasible, then I would wish for a second choreographic sequence. Split jumps, Ina Bauers and the like add some important variety to any program, especially for many of those casual fans we want to keep.
Either way, this new element could replace 1 jumping pass. The growth of quads is terrific, but I think the sheer number of jumps in free skates tends to crowd out other vital aspects of the sport.
Having 6 jumping passes, with 2-3 involving combinations, leaves plenty of room for 5 quads and a triple axel. Remove any rules governing repeats, and require only that a skater attempt each jump type at least once. Maybe we also could tweak the system to discourage eulers, which years later still look like a pop to me, and reward those gorgeous combinations that end with a triple loop.
It sounds like performing a fast, centered spin is more difficult than adding features. Perhaps the difference in base value between the levels should be reduced to prioritize GOE, in addition to raising the point value for spins overall.
