I am not trying to devalue BattleMaster's experience, nor drive people away. However, if what Ocean is seeking is not here, it is not right to try to deceive him into staying.
It is true that, if one were determined to play it as such, BattleMaster would permit one to play as a knight-errant seeking adventure.
However, if I am reading Ocean's post correctly, I do not believe BattleMaster would ever live up to his expectation, which is that such adventures would be provided to him by the game in a similar manner to a single-player RPG. To sustain such a play style, he would need to essentially write the adventures himself.
