To expand on this:
- What is the (solo?) content that players in the DMM version are striving to clear?
- How does optimizing to clear this content improve a player's strength long-term?
- What are the main focuses in the meta? Spike damage to get through a particular phase? Sustained damage to end a long fight more quickly (e.g., before a deathblow type of ability)? Certain defensive abilities? Are these focuses general-purpose, or would they be expected to become obsolete or marginalized in future content?
- How valuable are healing, cleanse, and dispel and other general utility skills (from kamihime)?
- How frequent is high debuff resistance?
- How often will a typical player have to worry about hitting damage caps?
- Presumably elemental advantage is a current focus. How does this affect one's ability to clear content and one's efficiency at earning rewards?
No one person needs to answer all of these, by the way. But a discussion around some of these topics might be useful.
