Honestly i am of the opinion that the content in this game is waaaay to light on heal requirements bar the very top.
Now i am going to do what people hate and compare it to wow and there if your healers have as much time to dps as here it means either of the two things:

1. You are straight up overgearing the content
2. You have too many healers, switch a healer for a dps

I love to heal and while i switch to cleric stance whenever possible, it is not why i chose the role to begin with.
