Does anyone know exactly how the hungry kunchongs handle threat when they max out energy and evolve? The dungeon journal states they will "ignore normal attempts to control them and attack any players nearby" and our tanks have said they are immune to taunts, and the result is they generally run amok mowing people down. However in videos I've seen them get quickly picked up by tanks and killed, even if the tank isn't nearby. Is it just a matter of actual threat? If so does it carry over from the hungry state? We have a druid and DK tank so options for getting non-taunt threat from range are limited. We're considering just letting the 1-2 people who get picked for mesmerize die quickly in order to prevent any mature kunchongs from spawning and keep all the damage focused on kaz'tik.
By the way, does anyone have a list of abilities that can break the mesmerize channel? I know spectral guise works, are there any others?
