I think the bigger problem with healer acc is there is nothing else to do half the time. Ex dungeons are so easy on the heals that I have to dps or fall asleep.

If they want to make healers heal then make them heal. Make more status effects to esuna, maybe use paralyze a bit more on heals/ tanks, heavy some dps before a big aoe mechanic. Make healers take care of the group to keep them at their best/alive. Maybe some more mobs which attack other players like the biast in Brayflox, just have it random aggro occasionally to keep healers on their toes. Not too bad to cause deaths so long as healer is paying attention/ tank re-grabs enmity quickly. This will have both healers healing and tanks tanking more instead of feeling the need to be so dps minded which is what it sounds like SE wants.

Right now it's simply too easy to heal in non-progression content that we should be dpsing as healers but having to meld just to hit in casual content is frustrating.
