I could be remembering incorrectly, but back when this was occurring no one knew that issue was specifically limited to "mob spawns attacked certain people". The more honest description is the line about "From the beginning of AC, some players have complained about unbelievably bad luck."

People blamed this behavior for everything from loot drops, to combat outcomes, and to aggro mechanics.

And also remember that AC was before MMOs became massively popular, and outside of specific events and locations, there wasn't always more than a handful of players in a certain area for a given server where aggro mechanics like this would matter.
