Hello! I just started playing the Live-version of the game a few days ago, and so far, I've been having quite a bit of fun! I thought I'd offer a few suggestions, though
1. The male Hyur -- Midlander and Highlander alike -- have some really awkward idle and running animations. I don't know exactly what it is, but they look a bit "goofy", particularly when sprinting. Something about their posture seems a bit effeminate.
2. There probably needs to be another more "masculine" race added at some point, just for the sake of variety. Hyur, Miqo'te, and Elezen are all very thin, very beautiful races, with the Lalafell and Roegadyn as the only ones that really stand out to me as appealing to different tastes. Personally? I'd love to see a race along the lines of a "humanoid Behemoth", sort of like Ifrit in some of the older games. Something that looks physically intimidating, as I could see something like that appealing to fans of other MMO's, to contrast the "pretty" races.
3. Personal opinion; I want to play as a Moogle! Just have their weapons "float" by their side, using magic and whatnot to swing them. Sure, it's purely visual, as they'd play like any other race, but they're just so iconic to the Final Fantasy franchise, it would be cool! Even if their Helm is the only armor they display, I would be all over that idea!
4. Clothing-customization. Customizing your character themselves is great, but I'd also like to choose my favorite clothes and armor. As long as you've equipped it before, and it doesn't conflict with your current Class, why not open those options up a bit?
5. Add a Grid-style UI manager. Instead of having to line things up manually, with overlapping or micro-managing every individual pixel, I'd love to have everything snap into a nice, clean grid.
6. I seriously love the idea of the "Lightning Returns" themed event. I'd love to eventually see similar events celebrate other games in the franchise, as well, provided it not get *too* overboard. I also love the idea of unlocking new Character Customization-options.
7. Some sort of multiple-characters utility. Maybe being able to trade soulbound-items between characters, or extending the catch-up mechanic for leveling up a different class to meet up with your highest-level, but also applying it to alts, as an option? I really like the idea of having two or three characters, not just using the same one to do everything, but I feel like you're just missing out on too much for it to really be feasible.
8. In regards to some above suggestions, I'd love to be able to start playing a new character, but visually outfit them with higher-level gear I've earned on my main. For example, if I earn the "Warrior of Light set" on my main, I'd love to be able to use its appearance while leveling up a new character, even if they're still just as weak as anyone else. I suspect some armor-sets simply look better on certain races, so that would be great!
9. Maybe consider bringing back a few truly iconic items that have since been retired? Many players are able to digitally upgrade their standard editions to acquire the new Collector's Edition items, and truth be known, I would really like to be able to attain the Onion Helm, as well as some other distinctive items that are no longer available. Of course, not *everything* needs to be available again; just things that aren't "status symbols".
10. There are a couple of unnecessary cases of ability-bloat (although not many!). Long-duration buffs, for example, I would personally change to be passive "Auras" for all friendly nearby players, removing the need for them to be placed as hotkeys. This also sort of leads into the next point...
11. The terminology of what constitutes as a "Class", versus what is a "Job" is just really confusing. Instead, I would advise breaking things down a bit. Instead, I would have *everything* listed as a Class, and listing the differences as "Base/Core Jobs" versus "Advanced Jobs" (or vice versa, everything lists as a Job, with Core/Advanced Classes) . You could even get all fancy with it, and refer to them as "Archetypes" and "Hybrids".
