"People are dumb and can't read so we had to stop them using the items" Thats what I gathered from it anyway.
it was those jewelries that keep breaking mezzings on "Yurit" in Matri Marn fights. it break and wake up Yurit. raids didn't want Matri Marn's undead healer spam heals Badum and debuff wipes.
The devs have repeatedly stated that some items are designed specifically with a certain playstyle in mind. Solo-obtained items will not be effective in raids, and raid items will not be that effective in solo play, etc.. The whole point of itemization in this expansion is that not every item is usable in every situation, and it is up to the player to select the optimal piece based on the content they are doing. That's not to say some procs aren't outright bad, but in the cases of things such as Blood for Blood and Aspect of the Dragon, they were not designed to be used in every situation, and any person using them in a raid probably deserves to be benched anyway.
