What is the context of this request?What is this user requesting?In this user's anecdotal and personal experience, it is much slower and more tedious to find players that are interested in either "learning" or "farming" the duty, "Memoria Misera (Extreme)", than other Extreme Trials, such as "The Dancing Plague (Extreme)", "Hades's Elegy (Extreme)", "Cinder Drift (Extreme)", "The Pool of Tribute (Extreme)", and etc.
My hypothesis, which lacks statistically-significant data, is that this issue is caused by Memoria Misera (Extreme) not offering sufficient rewards to motivate a large enough amount of players to want to repeatedly complete this content. This also implies that "dyeable Relic Armor" is not sufficient motivation for the majority of players to want to repeatedly complete an Extreme Trial duty.I would like the developers to explore the possibility of adding a more universal reward to Memoria Misera (Extreme), that would motivate a broader selection of players to want to "learn" and "farm" this duty, so that players who are interested in farming its glamours or items will spend less time trying to find enough other players that are interested in participating in this duty.
The suggestion of a "gwyber" is included because "yet another mildly-sparkling mount to add to your preexisting pile of 632 unused mounts with mild particle effects" seems to be a powerful motivator for a large enough amount of FFXIV players that almost all other Extreme Trials remain active, both "learning" and "farming", long after their rewards become outdated with regard to item level progression.
If creating another unique "gwyber" is deemed too costly in terms of development budget, perhaps the development team could consider repurposing an unused preexisting Garlean machine model, or perhaps allowing players to simply ride around on Varis yae Galvus's shoulders, perhaps with a Mount Action that creates harmless "Terminus Est" X's in the air.
