Quality of Life changes are part of every game, and here I am suggesting a bunch, I will try to be concise and explain the point for each, so bear with me, please!

Circular economy:

Circular economy was thought as part of the gamplay for certain items like Verus modules, Modification modules, etc. (same as costume stone enchants), but when phasing out that kind of content, it gets harder and harder to acquire them as you are the one that has to roll and farm for all of them yourself if you want to make an item from that content.

Suggestion: enable a better/faster/improved way to acquire Verus, 17.1 and 17.2 modules, for example, the ability of changing 3 randoms into a desired one from the same tier.

Tradeable items:

Certain items, like weapons from episode 18, can be turned into Amethyst Fragments. Wouldn't it be great for us to do that with other weapons too?

Suggestion: enable the turn around of

Sky Fortress weapons into Token of Honor
Old Glast Heim Challenge weapons into Temporal Fragments
Bioresearch Laboratory weapons into Somatology papers (either or both)

Guaranteed enchants:

Part of the process in this game is enchanting, but there's sevirity when enchanting older gear (very hard to get the perfect piece).

Suggestion: enable guaranteed enchants for

Horror Toy Factory for 400-600 Bloody Coins
Sarah and Fenrir for 20-30 Fragment of Gigantes
Thanatos Tower Sinful and Brilliant Accessories for 800-1000 of their respective pieces
Geffen Night Arena equipment (but I'm not sure about this one)

Tomb of Remorse:

Suggestion: add a pick-up and delete all button to Tomb of Remorse NPCs quest.

Dialogue speed-up:

Some dialogues tend to drag the narrative of the dungeon for too long, and they might be outdated content, but people like me and many others do enjoy playing them from time to time, but it feels kind of detrimental to even try.

Suggestion: speed up the dialogues for

Airship Crash (the beginning and the end)
Sarah and Fenrir (the stop-in interactions)
Sarah's Memory (the first 2 interactive dialogues)
Geffen Magic Tournament (the whole proccess to get there and talk with the NPCs)
Lost in Time (the talk from hidding and summoning the Pitayas)
Charlestone Crisis (the entire part when killing the marked mobs until the boss and leaving the dungeon)

Simulation Battle:

Suggestion: allow us to get the reward without sacrificing the instance's CD (same way it works for Room of Conciousness).

EDDA weapons:

Suggestion: to lower the Somatology papers requirement prices for the guarantee refines (could take more than 120 days with one character only).
