I would just like to point out the spell and the way it works doesn't bother me. What does bother me is the Impenetrable Defenses achievement. "Complete the raid without letting any of the animated armors reach Unfettered Emerald Excellence." If "You're supposed to kill them. It is very bad[tm] for them to reach the middle of the zone." and "It's a sure way to fail the raid." Then to me this would be part of the event. not an achievement. To me an achievement would be doing the event in a way that is different from the event as intended and in doing so make the event more challenging. If letting them get to the center is "very Bad " then maybe the achievement should have been to let one reach the center and still win the event. Just saying.
