Shadowform?
The lack of crowd control of the Shadowpriest concerns me. I believe everyone here agrees that the Single Target Mega Burst ability of the Shadowpriest is fantastic but in order to use it you need an opponent away from you. Psychic Scream is not enough to keep someone away due to the fact that it breaks with the First damage you do. Psychic Horror is nice but it requires Shadow Orbs to work. Still not enough. I'm mostly talking about melees that will stick on you.
Is it normal that everything I read about disc priests in WoD makes me want to cry?
I actually like all the proposed changes I've seen so far. PoM having a cast time will be a tad clunky to get used to, but otherwise I'm pretty stoked. Plus we'll have WOMPoM which will be great for Holy and Disc (probably encounter dependent.) They're also taking the time to look into how PoM interacts with itself and other PoM's from other priests which is really a much needed quality of life change.
Overall the healing changes look great.
As far as "just like MW now", MW's are fine outside of the last few fights on 25H, and even then you'd be fine to heal with them in that setting. It's just that other healers are currently bringing more utility or just silliness (looking at you Disc and more recently SH pally.)
In the end I suppose it will be the same as usual with Priests. We'll adapt and excel. :P
