an aura persists after the team lead dies

but if Packmaster dies, does Kro'khad lose the bonuses?  in other words, is Packmaster still "on the team" when dead?  if the bonuses disappear then that would mean they resume if Packmaster gets rezzed.  but if Packmaster is still "on the team" when dead, what if he was killed such that he couldn't be revived, does that change anything?

ditto for Hilvi and Tormin etc etc

and what about Ash'nar's perpetual?  he casts aoe HP Burn on his own team and it acts as a heal over time.  if he casts it and then dies, does his cast damage his allies rather than healing?

maybe I should already know this.  but some of these situations are not easy for me to test.  Ash'nar is usually last to die on my teams.  Kro'Khad pretty much always dies before Packmaster.  Don't have Tormin.
