Elite hunt marks aggroing in sarter zones! WTH?

Then why is it that the guards at the gates are not taking out these monsters when they are right in the middle of an area that is otherwise as dangerous as a sunny day in a playground? Even on a high population server there are not that many players outside of the HW areas that are high enough level to engage these monsters.

The levelled guards do actually actively engage with lesser mobs if they are in range.
To varying degrees of success. I've seen them ganked to death in places, but most of the time it's a one and done kill from them as they walk leisurely back to their post.
