Sheath of Light was likely found last because it was bugged for a lot of players.Even once its method of acquisition became public knowledge, many of us were not given an option to progress the sequence by Harold Riggs until a hotfix came in an hour or two after potential issues were identified. The fact that the Scarlet corpse was found on Newman's Landing well in advance of the full unlock process being discovered was testament to this.
we need at least 1 new rune per spec in phase 6
phase 1 - buggedphase 2 - all found in less than 48 hoursphase 3 - no one went for it because it was trashphase 4 - bugged follow up questbugs and undercooked content, SoD in a nutshell

The Metamorphosis one has to be the most annoying one due to the additional context: a lot of people went into SoD as a warlock specifically for that rune. For some, it was a major reason they even joined SoD. It was extremely short-sighted for them to tease warlock and rogue tanks just to put them behind a quest line at the phase's max level (25) especially when Shamans got it at like 13.Even though it was bugged, afterwards it was still the most frustrating to get done on P1 especially if you were Horde on a PVP server. You needed items hidden in places with elites, in ally-controlled territory (it says it's "contested", yet Horde has no FP or quest hubs there 🙃). The first part also happened to be locked in the BFD raid, but the bug was that the items dropped in the dungeon version of it. They eventually had to patch it so that you could get it from outside of the raid as well so that you didn't need to run the raid just to get the tanking rune.So much went wrong with that rune that it definitely affected the way runes were made and hidden in the following phases. Meta hands down.
I love that you included the meme I made from Phase 1 for Metamorphasis, thanks for the creds!
Didn't the priest cloak rune Soul Warding also take up quite some days?
