I think it'd be better for someone who has quite a bit more experience with the game to comment. However out of the three characters I'm learning to use, she is the easiest (I'm learning Kyo and Elisabeth). The key with the dp+P to dp+K cancel is ensuring that the last input is at
you can hold that to make sure it comes out, or put the stick back to neutral. I feel confident in my execution for that now, after that it's practice, like this HD combo: d.B, d.B, s.B [HD] s.C, dp+C [DC] dp+D~C, [dp+A (DC) qcb+C, qcb+A]x4 qcf~hcb+D
Compared to the other two character I'm learning, Liz has timing that can be a bit hard to get a grasp of. And Kyo has some hard moves to pull off, mainly dp+P to rdp+K cancel, and some others as well. Yuri doesn't have a lot of funky stick movements in my opinion.
Like my first post here, I think once you get the dp+P to demon flips cancel down, you'll be able to get the most of of Yuri. A lot of her HD Combos rely on that cancel, once you get that, it's just practicing the rest. I'll agree that HD butt loop looks like it needs lots of practice (Youtube videos make things look easy). Overall though I think she has easier execution than at least Kyo and Liz at my current level of play.
