Those system would not only introduce more horizontal progression, but also more customisation (which is something players seem to ask for a lot lately). In order to avoid affecting lower difficulty content, those could also be disabled and kept active only in high difficulty content (acting a little bit like a soft nerf on the content) and in open world content.

There are a lot of other options and systems which could be implemented. For me, experience is important, levels are not, and sticking to a classing leveling system for a game like FFXIV will strip the game from it's uniqueness.

Feel free to give your opinions and ideas, I would love to hear them.
