So far, it doesn't look that way. On THM Sacrifice is gone, all the astral/umbral magic is gone, and no new survivability tools seem to have taken their place. So that makes two different classes to level up just to be able to move from one fight to the next without a lot of downtime.

Both DoM have undergone massive, radical transformations that may even make gear people had yesterday obsolete.

I realize that the main reason for such sweeping changes was to make each class more unique, but people have their reasons for picking certain classes, and the resulting virtually new class might not live up to those reasons, undoing a lot of work even though that wasn't their intention.
