In early dragonflight, it was noted that disc and holy would be the only 2 specs in the entire game with absolutely no access to an interrupt. Two stated reasons for this are:
1: “Having access to an interrupt is not something we view as necessary for all specializations.”
2:“In PvP, Holy and Discipline already provide valuable control to their team and additionally having Silence would provide more control than we’re comfortable with”
Yet in TWW, interrupts have become the ONLY way to put a dangerous mob ability on CD, and we have even seen bosses like Candle King in Darkflame Cleft, which spam-cast potentially group wiping abilities every other cast. As someone who has been playing both priest and monk this patch, the difference in enemy control is absolutely insane. I understand that blizz is concerned about how holy/disc interrupts would affect PvP. But their PvE enemy and encounter design increasingly inches toward making interrupts absolutely mandatory. I can feel the lack of PvE control that I have in every single dungeon, and it can be quite miserable at times.
