I don’t care what anyone says, I’m not budging on this, and I’m not interested in being convinced otherwise. Every other title shown in the Travail Teaser has already manifested in-game exactly as presented. The Sumeru title is the sole exception. There is absolutely no way that omission is a mistake. In a teaser that deliberate, consistency everywhere else only strengthens the implication that this deviation is intentional.
Reminder: Sumeru is still due an Archon Quest!
