(Relics) What is the lowest-development-cost content we'd still find fun?

Back to the OP's original question: The merit system from XI.

All 80s and nothing left to do? Grind yourself some bonus stats. An extra 1% bonus damage on certain actions or weapon skills, for example.

The merit system from XI would not require any asset changes - it would only require some damage calculation changes, some additional tables on the characters, and a few other programmatic changes in the game's service layers that don't actually require the art team, the lore team, etc. UI team would need to get involved for a menu change, and that's it.

Oh, I second this too. Meriting always felt so much more rewarding than leveling or even getting gear sometimes.
