So this is the source of your anger about current lore? Your continuity is shattered, because of that one tiny event from over decade ago?
Here is your expelnation:
"Shortly after his brother's death, Robert sent an e-mail to request a character be created in his brother's honor. Chris Metzen, who had attended Brad's funeral, heard of this and suggested two ways: to add him as part of the main storyline for Wrath of the Lich King, or to give him his own epic quest chain. Under the direction of Metzen and Alex Afrasiabi, the Bridenbrad quest chain was created in tribute to Brad Bridenbecker's battle against his illness. The quest chain can be viewed as a fairly detailed metaphor for the ups and downs of battling cancer, and for the process of dying in general."
