Brayflox is the first time the training wheels come off for new players that is kind of the point. Figuring out to beat Aiatar is the very first lesson you need to learn in FFXIV it requires you to work as a group. Making it easy to faceroll after failing a few times and not being able to handle it kind of ruins the point of progression. Echo in endgame is already a long debate if it's a good or bad thing don't need to make it even easier to level for new players by holding their hand the whole way. Before that the games dungeons and guildhests teach you the basic mechanics. Players have all the tools to win that fight already.
