Note that there is a known issue where boss health and other stats are currently not scaling with raid size; we're adjusting the boss's health to be appropriate for a very large raid (so that it doesn't fall over immediately for large groups), but this means he likely won't be killable with a small group. So please don't worry about the health tuning. Other mechanics should still play out as intended.
