In my experience, the expanded healing kit is only necessary if you're interested in doing dps.  That's the baffling bit.
In expert roulette, for example, with wall to wall pulls, I still spend ~60% of my time spamming Art of War when paired with the average tank.  That's because I am utilizing our new abilities like Seraph and Recitation (and the busted new SS).  But they're entirely unnecessary if my goal was to simply keep the tank alive. 
It's why, SE, I am confusion.  You give us all these admittedly nice healing abilities; you take away most of our damage kit; we take those new healing abilities and properly utilize them; proper utilization leads to healers DPSing for a large part of their time in group content.  So we're still DPSing the same amount, healing a bit more, but are all the more bored for it because we spam 1 button.
