I mean, there are so many examples of this flip flopping out there (with any class really). In tier 10 everyone thought shield spamming Disc was the only way to go, and yet, world first Paragon LK vid has footage of a HOLY priest in the raid. Smiting even. Yeah, there are Disc priests there too, but they were basically needed for Infest, good spec or not. Tier 11 rolls around, and Disc is "shit". Yet, heroic Nef world first vid has nothing but Disc priests in it (yeah, they were using Disc for Barrier, but all people ever obsess with is WoL numbers, not like, real world application). Holy was "shit" in tier 12, but world first Rag kill was 3 freaking healed by a Holy pally, Resto druid, and a Holy priest. Tier 13 Disc was supposed to be shit again, at least according to raidbots, and yet there are no shortage of Disc priests in world first kill vids for that tier.
