Why sts didnt make a partner (Helm, Armor) for this cool 71 BsM Elite Weapon??

I think this 71 BsM Elite Weapon deserve to have a set in my own opinion or Change its lvl to 76 and be partner to Savage, Swift or Sharp so everyone who finish the quest would love to use this.. Like what sts did in 71 Humania Elite (just a suggestion)
