Rift Bosses
I have now done 3 rifts so far, all unstable in which the final boss should be Namor, but 2/3 times it has been Invisible Woman. The 2 rifts I have noticed this on have been Heroic difficulty for the Unstable Rifts.
Is this intended or am I accidentally opening the wrong rift and not knowing it?
I do not have any evidence but next time I open a Heroic Rift I will make sure to record and update this discussion.
