So tonight while doing my weekly Black Temple run for the warglaives, i noticed something i hadnt notice before. When Illidan hit about 10-15%, Maeiv placed some sort of mechanical engineering box- like thing on the ground. Just out of curiosity i drug Illidan over to it before he died and when he did, it made blue energy fields around his dying body, then proceeded to close. And Illidan's corpse laid on the ground like normal.
Was wondering if this is something that happens every run and i just dont pay attention, or maybe something they added in 5.1. Real curious though with all the return of Illidan hype. Hope someone can confirm that theyve seen this as well!
