I get the feeling you don’t actually main a shadow priest, because twice now in response to my posts you have said “Shadow is just smash void bolt” which couldn’t be less true if you tried.
The reason shadow got nerfed is because dot classes are incredibly hard to balance for cleave based fights. We’re not the only class that got hit either, but the issue is that shadow generates such a massive increase per target because of the way that our classes is designed that it makes it impossible to nerf the cleave dps without utterly trashing the rest of the class.
You seem to understand some of the issue, but rather than actually talking about the problems you just use buzz words like “broken” and “toxic” and you devalue the spec to one button spam, but then also acknowledge the incredibly leverage that proper insanity generation has.
Voidform is NOT a bad system. What it’s current state is however IS bad. And that’s mostly because a lot of the things you refer to, Chorus of Insanity and Lingering Insanity, used to be baseline parts of the shadow spec. During Legion Shadow priests had access to two things: Lingering Insanity was baseline on Shadowform, and Xal’atath had a golden trait called Mass Hysteria that gave us 2% dot damage for each stack of void form.
Chorus is the new Mass Hysteria, and Lingering Insanity was moved off voidform halfway in Legion and made a talent, which was one of the DUMBEST things they ever did. When you take two things that used to be baseline for the spec that made it work, and put it as “optionals” that players can pick, it becomes REALLY hard to make meaningful choices outside those, which have been tailored to the spec from the start.
The problem with voidform is that they have never sat down and bothered to redesign it properly from the ground up. They just took out pieces of what made voidform work from Legion launch, and put them in separate pieces so they can tune those pieces and balance them individually.
There IS a problem with voidform1 being your build form, and voidform2 being your damage form. There is a problem with M+ performance for Shadow. But that’s ALWAYS been the issue for shadow. You can have voidform be interesting and fixed without throwing it away for “shadow orbs” which was the lamest thing shadow ever had, and the least interesting class resource since holy power.
At least we can identify the issues with voidform and fix it without trashing the form. They just actually have to do that instead of constantly holding on to the original spec in several pieces.
