Progression system that could improve endgame (By a lot)

[koko-on-da-forumz]

It isn't a systems restriction. Relic weapons originally had special effects associated with them but the feature was removed later. We have literally had this in FFXIV before.

The issue really is that we have no content where it's relevant.

XIV is first and foremost a visual novel, and after that it's built precariously for raiding. Every other thing you can do is molded so that the raid kit they designed can function in it. And raids are just "do damage" and "stand here". We can add elemental effects like blue mage or vampirism on gear, but it's not relevant to any content unless they create one where it's part of progression.

This is why deep dungeons, blue mage, and exploratory zones are the only parts of the game I enjoy anymore. It's the only place where there's a degree of fluidity and experimentation. Even then, the latest updates on all three of those have been leaning more and more rigid and raid-like.
