kinda surprised mind sear wasnt turned into a baseline ability, it's really obnoxious how many runes i have to change when going from aoe to single target and it's honestly a travesty that a spriest should ever not have shadow word death on, it's such an iconic ability that lets you actually try to get spirit tap procs in raid to move from pack to pack faster
Lots of classes bring utility, warlock curses, pets, soulstones, shaman totems, mages can heal and do damage as a viable dungeon healer and the parse is neck and neck with Spriest. Only time I've healed as Spriest was with another Spriest and still we had to pop out of Shadowform to spot heal or boss heal in dungeons in Vanilla.It's sad I love the general style and feel of Spriest, but why bring an Spriest when you can have an extra healing priest go shadow for a fight or if you have a spare heals in raids?
You can go other way, and make raiding really miserable without shadowpirest utility
