Why is Koten Zanshun (Orihimes attack from Bleach) unsucessful?

Question

Ok lol so does anyone know why it most of the times failed. Besides the 3 times it actually cut something? Lol shes one of my favorite characters and I really really like her powers. But how come it barely ever works :( ? Like I know it's powered by her emotions and stuff. But when she was really mad and determined to win and used it on Yammy Espada 10 he smashed Tsubaki into bits :(. Lol is it cause her attack is cutting instead of like a blast? Maybe they don't want to show Orihime cutting someone in half or something? Cause I find that in the games she is one of the best characters cause she can block attacks, while healing and attacking at the same time! Lol. Plus in most games everyone has about the same attack power so her Koten Zanshun isn't downgraded like it is in the show. Uhh sorry that this was soooo long lol!

Answer 1

because, Koten Zanshun has no experience.
