Logan Thackeray is one of the potential end boss fights in the Chamber of Nightmares mini-dungeon. This single factor may make this one of the most popular updates in GW2 history. In my guild, Logan’s popularity polls around that of Rurik, so the chance to kill him is celebrated.
Logan is, however, a decent opponent, rather than being completely useless, and I do not recall him whining at all. This makes it entirely too obvious that it is a hallucination.
