Not one webpage, any webpage, including all the ones you cited. And I didn't say anyone was wrong for certain. For someone accusing another of not reading, you aren't doing such a great job of it yourself. I said:
- It may or may not have.
- The evidence was lacking.
- The evidence was lacking for a reason.
If no one posted anything about killing him, including that he was killed at all, because he was a giant secret, then he is the only raid content that was secret enough not to post about. Because if that were the case, there wouldn't be anywhere near the level of documentation on raid level encounters and everything even remotely associated that there is. But we both know that simply isn't true.
Anything that was raided (alongside tradeskills) is the most heavily documented content in the game, in any era, regardless of the amount of competition for it.
