The Rankers' Code of Conduct in Anfang dictated that the Grandmasters share their insights into their Ranking Journey after their recent breakthrough into the A-Rank.
This sharing of insights would serve as a sort of compass for their juniors.
For example, Grandmaster Amory shared the insights of his Ranking Journey when it was his time to address the audience during the event that celebrated his breakthrough. Amory's insights were accepted by the Rankers who had similar Ranking Paths as him, enabling them to benefit from his experiences.
However, Eren's speech didn't include these insights. Instead, he focused on making Rankers go through a phase of self-reflection.
This was rather contrasting because Eren could share insights that could be applicable to almost anybody. One could say that his insights were, in a way, globally compatible with all of the Rankers of Anfang. They would have benefited most of the audience if not all.
