Trial Cosmetic VFX

Greetings everyone ! I would like to make an appeal about the 30 Days VFX (killing streak effects). Since we are paying 4500 Orbs for, basically just a Cosmetic, why we cannot have those effects permanently? I really like those effects, but its sad cause we cannot keep forever.. Blizzard, Netease, please think about it, some of us are "Cosmetic Hunters" and its a pain 🥹
