Your options being gutted doesn't mean your damage is gutted. Biolysis does 50 more potency than Miasma 2 and Bio 2 combined. Broil 3 obviously does more damage than Broil 2. Having to maintain 2 dots over one isn't any harder or more complex -- healer DPS kit isnt, and likely never will be, complex. The complexity of playing a healer at high level is mapping out your heals to allow you to Broil/Stone/Malefic spam more. That aspect of the game hasn't changed.
EDIT: The saddest part of the media tour info is that there isn't as much unavoidable/hard to heal damage as I would have hoped, but I dont think the playerbase is ready for unpredictable/near constant levels of healing. At least not immediately. It's something that will have to be slowly introduced.
