The whole purpose of archery is to attack from an advantage point. You still had to climb down and go into the camp to grab the thrall. And if we are going to remove that part of archery ilon NPCs, then guarding thralls on pvp servers should get the same reset so you cant cheese them during raid hours when offlining. You can basicalky spam arrows from out of ramge of guarding thralls to kill them with no worry of death.
