1. Maybe it's just me, but I don't feel all jobs play the same. They are all based around a 2 minute burst window, but I cannot agree on a Samurai playing or feeling the same as a Monk or a Dragoon. Dancer, Bard and Machinist also feel quite different to me. The same goes for magic DPS. I believe tanks suffer most from this issue. And healers too, but only their DPS related stuff. So I do see problems in those two roles, but even then, in my opinion they still feel different enough.
2. Custom building sadly is an ideal that will never really exist in a game where performance is measurable in numbers. There will always be a best build for a specific situation. I'd rather they removed the little customization there is(materia), because "use xy skill speed/spell speed or your rotation is busted" does not add any fun in my eyes. Now if you're talking about stuff like... alternative skill animations or colors? Or even entire alternative skillsets that function the same, but look different? THAT I would be into.
3. Outdoor monsters are HP sponges existing for specific side quests or to prevent the world from feeling empty. I too wish they would be mechanically more challenging and engaging, but I guess their focus has never been to be dangerous. They are supposed to make the world feel more alive. And it shows xD.
4. They might have gone overboard by redesigning crafting jobs THIS much. The HW system did have flaws though. i.E requiring you to level up ALL crafting jobs, because they had cross-class skills gated behind specific jobs that were basically mandatory.
5. Those blue gear options are necessary, because not everyone wants to buy crafted gear from the market board or craft it themselves. Also not everyone wishes to pentameld. Blue gear from normal raids is supposed to be an alternative, and it does this quite well. It also offers its glamour for those who do not do savage. Unless it's only the coloring you are refering to? Because that IS kind of weirdly color-coded in the crafting section. The issue being that NQ Crafted gear is inferior to the raid gear equivalent, so the color is actually correct. But the HQ version is better / equal, so it makes no sense. I believe rarity color cannot be different between NQ and HQ. Maybe that's why they went with color-coding it like that.
6. Side quests are... uhm... yeah. They exist xD. Some of them are pretty good. But most of them are filler or meant to show daily life issues. They make sense the way they are. They're just not very engaging.
7. FATEs. Well... yeah. They are blunt and every expansion I hate myself for grinding through every single zone, because I want full access to all the FATE vendors -.-.
8. I honestly don't mind they quit this part of the game. I never liked it. Squadrons are fine for what they are, but I'm glad they are not opting to gate content behind those - which they would have to, if new ranks were introduced.
9. I have mixed feelings about this. On one hand I like it when games have stuff just because it makes sense for it to be there. Not everything has to have a purpose. Because if it did, zones could start feeling like unnatural, stale ubisoft open worlds, where verything exists for the sole purpose of being interactible by the player in some form. But I DO wish there were incentives to visit some zones more often, or to explore them more thoroughly.
10. I don't pvp, so I have no opinion on that section >.<.
All in all - I do see wasted potential and areas the game could improve upon. But bottom line I still like the game and what it offers, and I do not feel like it's being neglected or treated poorly. I can see a lot of effort and attention to detail going into it, and I appreciate it.
