FEEDBACK: Hellfire Assault (Heroic)

Please use this thread to provide feedback, bug reports, and other discussion of the Hellfire Assault encounter. At this stage, feedback on mechanics and clarity are particularly appreciated. When offering feedback, it is also helpful to describe the nature of your group (Mythic guild raid, Heroic guild, PUG, etc.).

If you aren't seeing trash spawned in your instance, zone out and back in. You'll need to clear that before engaging the boss encounter.
