Hey,
As a foreword: This is not a complaint on difficulty of content. Clearing mythics is not an issue. I dislike the way healing feels right now.
I wonder if anyone else here finds healing quite unrewarding currently.
To elaborate:
The main fault I find is the designed inability to save people from large damage spikes outside of Major use of CDs.
Health pools greatly out scale heal amounts and tanks are now mostly responsible for their own safety.
Since the healer is in great difficulty to compensate for other player's mistakes at large health loss spikes, the only job left is to slowly pad health bars, small bit by small bit.
This does not leave me feeling like I am saving people as such but rather stiching them up a bit.
Boss fights are often very two- dimensional :
Either people do mechanics well and it is quite boring to heal, since there will be little damage at all.
or
Mechanics are not followed and party-members take such large amounts that the menial heals often wont be able to compensate in time and they die regardless.
This is all from Mythic dungeons in 840 gear Resto shaman.
I am still hoping that this paradigm might shift with scaling. So far it has not been a satisfying experience I find.
