BCNMs in FF11 were pretty fun. They provided content that was accessible to people long before they reached the level cap, and the rewards they offered were often valuable and relevant for very many levels, in some case all the way into the max level endgame. It made new players feel significant in a world that was populated by lots of people way stronger than them, and that's probably the best part of it.

The downside was of course the need to carry gear sets for multiple level ranges for several of your jobs, which quickly ate up a lot of the already limited inventory space of that game. Level sync with automatic gear scaling alleviated many of these problems. Too high level gear wouldn't be come useless, but correctly leveled gear would still give you a slight edge. This lead to, at least for me, keeping around 2-5 pieces of gear that would be good for many lower level ranges, while just using auto-scaled gear for the rest of my 16 slots.
