Mob Ogron Hauler reproducable combat bug

mob: Ogron Hauler
where: during Assault on Ironhold Harbor in Tanaan Jungle
what: occasionally hits for 1000 * normal damage and 1 shots you.

This has happened several times now. The mob hits for ~500-800 about on par with an elite in the area but weaker than the boss mobs. Every now and then though it does a support ability “interrupting shout” that hits for 58,000 damage and one shots you. (if you’re level appropriate for the area)
