Saw another mob go white while engaged yesterday. We were trioing Ovni NIN BLM WHM (no one else around to do anything to mess w/ hate mechanics). Only the ninja was engaged. He remained engaged for the duration of the fight and was not back tanking. I guess it's possible I took hate on BLM but I was 17 away (and standing right next to the WHM) from Ovni, well within the range that he would have just moved to hit me and not deaggroed. In between melee swings by the ninja Ovni went white and then was reclaimed the next hit. I don't remember seeing engaged mobs go white before maybe a year ago?
