Orion has confirmed it's a bug

Same policy as the previous. Spread the word. Do not farm it, kill it if it is in the way or gets in your way during a battle, fine, sit there and kill it over and over again.... no.
Let's just stay away from it :)
Perception is reality... last thing I want is BAOS accused of what looks like exploiting. No real reason to engage those guards anyways except for DP and loot.. both of which we can get elsewhere.
Not speaking of the Seargent forced spawning, but some on the main forum make it sound like drawing the EC npcs back to the bridge and having the bridge guards help you kill the freep npcs is also under the "bug/exploit" umbrella.
If that is the case, I will disagree. First if you run past the apex of the bridge (highest point of the arch) they will reset. Second, if you are off on your timing, the patroling guards will be on the TA side of the bridge, so all you can so is reset them or die. Then again if they are just talking about the Seargent, never mind all that ^^ :D
Yup. :D
In these games, all it takes is sometimes one or two people accusing a person/guild of exploiting, and your reputation's ruined. :/
