it says tyrael is tormented by nightmares of heaven's destruction by diablo.
it says the court of justice was his former court.
it says he struggled living with the angels as a mortal.
question is who is the new archangel of justice? can an angel just change his title from justice to wisdom?
because bear in mind that each was formed from the crystal arch with a trait and represented it with his title.
when he dies, he is reborn from the arch and resumes his position. if tyrael changes just like that to be wisdom presumably because he gave up his angel status, then wouldn't there be no replacement for justice?
also if an angel tears our his wings and gives up his status then he becomes mortal...isn't that a weird way of becoming mortal? mortals/nephalems were born from angel and demon. not from an angel tearing out his wings.
