I didn't (and even don't)think hunters had (have) stealth or shadow form or mode. Hobbits and Elves have hobbit-stealth mode and elf-shadow form. Do you mean hobbits and elves can enter stealth/shadow mode/form? Please be specific and help me find my hunter stealth/shadow if I am wrong?
Mysticraiders said, "If you're a hunter you can enter shadow form and creep within quest-acceptance distance (maybe 1.5 meters) without aggroing the 3 elite giants standing just behind him."
