Well pretty much common sense i would say but I hadn't thought about it till today and thought of sharing.
Hunters have the aspect of the beast which apart from giving u and your pet 10% melee ap it also makes you untrackable. So this might save you from another player in the middle of the night who happens to have track humanoids up and spots you and either kills you or reports you.
I know this isn't much but at least it shouldn't be a repost :P
