I do think Jason Brown-type skaters deserve to be rewarded, but the thing is... he IS rewarded! Winning silver at 4CC without a quad is an amazing coup! (I think Kostornaia is a somewhat imperfect comparison for him in the ladies' field because she remains competitive with Trusova and Shcherbakova even without quads--though you could say her execution of the jumps she has is better than theirs, and of course she has a 3A. The fact ladies can't include quads in the short helps her massively here, so the artistic/technical division is already in place to an extent... The ISU could just extend it to the men's event if they like its effects.) The only issue is that skaters like him need to build up a reputation with the judges before they can start getting the PCS boost they deserve relative to other top skaters, which may sometimes take a couple of seasons.
If anything, someone should take up Kihira's cause because her jumping technique is cleaner than any other top lady's (including that of Kostornaia, whose Lutzes and Flips are sometimes suspect), but that's not reflected in her GOEs.
Also, regarding spins, which were mentioned earlier... It bugs me to no end that the best spinners do not get rewarded for their superior skills. I get that jumps are harder and really should be worth more points, but it's appalling that having better spins than anyone else in the field is worth 1-2 points at most. I think one way to address this would be to increase the BV of L4 spins and rework the criteria so that slow/travelling/laboured spins can't qualify for that level. But IDK if the judges would use the GOE as intended if that happened.
As you can probably tell, I find the way GOEs are currently awarded more problematic than the PCS... I don't think GOEs allow for meaningful differentiation based on element quality among the top skaters as it stands now.
