I still don't understand why any of these glyph/pve/spec changes were made at all

you mean the same guy who originally said no to buffing paladin? the guy who wrote and entire wall of text saying why they weren’t buffing ret?
Its an easy thing to fallback on but its disingenuous entirely. He said no originally, that breaks this entire narrative. If this narrative were true it would have just happened without him posting saying it wouldn’t.
