Game Design Uth Shrine/altar - Ranged Mobs Wasting Avia Feathers

(I hope I've put the thread on the right topic this time)
It was always annoying when a ranged mob accidentally kills another one and prevents his drops, and, instead of fixing this, Wynncraft made the problem worse: if you go to the Uth Shrine, sacrifice a feather, wait for the long cooldown timers and waste your time fighting all the way to the Uth guardian, there is still a big chance that the ranged mobs will "accidentally" kill the Uth mob and prevent it from dropping the runes, meaning you wasted not just your time but also the feathers. Please fix as soon as possible.

Ah, and when/if you fix it, please fix the ghost items that the mobs drop (if a mob is killed by a ranged mob, he'll drop the item he is holding, but it will be unpickupable, almost like a visual glitch)
