Word! ITA...How do you know what they do or don't focus on? I think this is attributing motivations to skaters that they may not have, based on how well their style works for you. My memories of Stojko are by now pretty hazy, but Plushenko had some lovely programs in the past and both Joubert and Reynolds have tried to improve various aspects of their skating. Joubert did not skate a Flamenco SP and Beethoven LP two seasons ago, or try the Inception LP earlier this season, because he wanted to showcase his jumps. Reynolds' work with Shae-Lynn Bourne does not suggest to me a skater who doesn't want to improve his artistic expression; I find him greatly improved in that regard.
Skating skills and transitions are not artistry; they can enable artistry if used correctly. And artistry is a very subjective thing - of your list, for instance, I don't feel that Chan and Hanyu are anywhere near Buttle and Takahashi at this point in their career. My reaction to Elegie was basically "Chan has a lovely program, well done him, but it would be nicer if Buttle skated it himself".
