Hunter's Aura, as well as Mirage's debuff (and probably crippling headshot from my testing) do not show indicators where other debuff indicators show on guardians & walkers, such as mystic vulnerability, mystic slow, and toxic bullets.
They seem to instead show at a static height (in the chest of guardians, hiding them form view almost all the time) and below the abdomen of walkers.
