We've seen quite a few requests for ways to enhance artifact armor and other equipment.
You'll be happy to know that the development team is indeed looking into this, but their current priority is content related to the August version update.

As a matter of fact, Producer Matsui Akihiko commented on a couple different occasions already!

  • Expansion of synthesis and other non-battle content
  • Continued adjustments to reives
  • Addition of solo-content that focuses on exploration instead of battle
  • Adjustments so that players’ efforts are more naturally tied to colonization
  • Revamps and enhancements to equipment
    RMEC weapons, job specific equipment, etc.

To start off, we'll be placing a heavy emphasis on increasing the amount of content variety, supplementing the gaps in content, and making it possible to increase your item level solo or low-man, and we are proceeding to prepare for the implementation of a lot of this.

As we are in midst of working on the July version update as well as the August version update, I'll need a bit more time before I can tell you new information, but I’ll be doing my best to deliver it to you as it becomes available.

We'll let you know once there is any progress on this!
