It amazes me that you want to criticize Yu-na when to be quite frank a lot of the people are using the double axel sequences to gain points on Yu-na. Yu-na could do a 3lutz/2toe/2loop, a double axel/3toe, and a 3flip sequence double axel and her base value would almost be same. Mao only does one difficult combination in her program a 3axel/2toe. Yu-na goes for two extremely difficult combinations in her program (more than anyone else) And yet you want to criticize Yu-na.
I mean did you look at Miki's layout? Everyone's doing the 3flip seq double axels now. Why go for something more difficult like a double axel/3toe. Or even harder a 3lutz/3toe. But right Yu-na's the problem because she chooses to do a double axel instead of a 3loop (Just like Mao absolutely chooses to do a double axel instead a of a 3sal or a 3lutz) Yu-na is literally the only person in the top 5 who even went for a 3/3.
