Actually we are saying that the class isn’t fun to play and doesn’t function, at least according to Heylaa. My viewpoint, based on both Legion and BfA gameplay so far is that it DOES function, but that they are QoL issues and a lack of choice in talents. It’s important to note that choice is from TALENTS themselves, not gameplay.
There’s a lot of choice in gameplay. And there used to be a lot of ways to have the shadow priest showcase themselves with that choice. But over time that choice has been diminished as the upper limit of voidform stacks began to be capped by the changes.
A lot of that is because the talents now have too many required talents to make the spec feel good in content. With those choices, it feels just fine. But if you deviate from the choices, it feels bad. So essentially the issue lies with how the spec should feel outside of talents. For there to be more options the issues present with the shadow priest has to be addressed.
It should be noted here that shadow priests are NOT the worst damage. At all. They have quite respectable raid performance and had a lot of good presence for a while. BUT they have some shortcomings in M+ dungeons, and shorter uptime fights. Because the class feels the best and most fulfilled having uninterrupted uptime on 1-3 targets that are closely grouped, there needs to be something that bridges the gap between that kind of gap.
And this is NOT a voidform exclusive issue. The same thing happened in MoP. Shadow did too much damage on multi-target boss fights, got nerfed, and their single target and short term fighting power suffered. It was also a problem in wod too. The class is NOTRIOUS for breaking cleave based fights, with or without voidform.
For me, these are the issues that I have with current shadow priests:
Lack of meaningful talent choices, there are too many that are mandatory.
The class feels awkward outside of their optimal target situation.
Not having void form available for trash pulls in dungeons is bad. You either have no insanity and miss out on the better part of the damage, or you have to save insanity and sit in shadow form capping insanity for the next pull. This is a choice we shouldn’t have to make.
These things can be addressed and still keep voidform. And voidform doesn’t have to retain literally everything about itself either.
But the answer is not to go back to a boring system or orbs just so you can feel like you have more choice. There’s a lot more choice in the gameplay of shadow, and none in the talents. Going back to orbs would remove choice in the gameplay and MAYBE add choice in the talents. Not a tradeoff I want to see.
