I agree. People need to get away from the impression that supports are just there to stand in the back tossing heals. I'm hoping monk is compelling enough that the meta will become a little friendlier to the currently unpopular supports.
The ultimate could be nice, but I'm not sure considering if you can keep them alive through healing why do you need a resurrect. The reason healers are currently more popular is because they are effectively a cushion. If someone makes a mistake and takes damage, healers can come in and save the day, Tyrande and Tass cannot do that. With that in mind you're making it harder on yourself by not having one. Until the benefits of not having an healer outweighs or is even towards the benefits of having one, why wouldn't you take one?
Now to solve that problem I feel like a lot of changes needs to happen. Healing needs to be reduced on the healers. Some damage may need to be reduced, or it needs to be more avoidable in the first place, but not sure about that one.
