Greg "Ghostcrawler" Street has been taking part in an interesting discussion on the official forums that focuses on health and healing in Cataclysm. Here's what he had to say on the subject:
"Health pools will be much larger in Cataclysm and healing will be lower. That should help address some of the overly binary feel of PvP and PvE encounters. You'll still be able to kill people as well as be able to heal them. The pace will just be a little slower and both healing and killing should require more than 1-2 buttons."
He elaborated on his comment a little later in the thread. Basically, efficiency among healers will matter more, while maximum health for tanks will matter less. Avoidance for tanks will become a little more important since it will allow healers to conserve mana.
What do you think about Ghostcrawler's comments? How do you think this will affect both PvE and PvP?
