1. Incorporate some kind of 4 and/or 8-person party grind option similar to those found in FFXI as an alternative to FATE and dungeon-grinding

2. Rather than Warcraft-esque "raids" like Binding Coil, why not bring back things like Dynamis, Limbus, Salvage, and Nyzul Isle?

3. Bring back BCNM, KSNM, ENM, ZNM, ISNM, etc

4. Make gear with lasting power. Adding useful set bonuses like increased radius on Flash or increased duration on Regen when you're wearing full artifact gear would be awesome

5. FFXIV needs a sense of community. It was a huge letdown to obtain all five pieces of artifact gear by myself over the course of 2 five-minute quests

6. Other honorable mentions include Sky/Sea-type areas that are only reachable after the completion of difficult missions; HNM camping for those of us with too much time on our hands; 2hr abilities or something similar; Race-specific equipment; Skillchains
