Also, the time until enrage for each boss pair?
I beat them solo at MP6 a few days ago:
The King of the Dead 39.636.600
The Merciless Witch 28M
The Undying One 36M
I didn´t catch Siege´s HP solo, although I remember that he had 167M at MP6 in a 4 player game.
You could apply the % HP chart from the blog to figure out the rest.
