Perhaps, but here's the thing. WoW's raids are the way they are because the crew at the very top were former EQ raiders. It was their passion. That is why WoW has always had the best raids. Doesn't mean they have the best everything else. Every MMO is weak somewhere. There is a finite amount of resources and manpower available for every MMO company to use. So if SE focuses more on raiding, some other area will suffer as a result. I'm not really sure people would be in favor of more trash in raids. Not unless it had a 1-5% chance to drop some kind of decent loot.
Either way at the end of the day, it's not really that smart to design content for at best 10% of your playerbase while ripping manpower/resources from other things.
Why would I go through the trouble of digging through 1000+ of your posts to find it? Surely since you're the one who made the posts, you can remember what you said no? Or at the very least you'd remember in which posts you stated solutions. Sorry, not digging through every one of your posts.
As far as raids go, there really are only two ways to do everything you can for raiders. They could make more raid bosses per three month cycle. They could also increase the difficulty to give raiders the illusion of time. If it takes them almost three months to beat ultra difficult raid bosses they will complain about the difficulty instead of lack of content. FFXIV's raid bosses that exist have already thrown so many different mechanics at you, and some people say there's no innovation there, /shrug.
But here, I'll throw out my ideas concerning PvE. This is actually something probably not possible in FFXIV at this point. My idea is to give more power to players. I'm talking about the ability to create mods, outfits, skins, and even maps. No official MMORPG I've seen does this(with the exception of mods.)
A little "game" I've played before called Second Life allows you an unparalleled level of customization on your avatar. This is because they allow players to create outfits, avatar accessories, skins, hair, etc. I'm thinking if an MMO allowed this there would be a lot for crafters to do. They could craft design skins that may or may not sell well depending how popular their design is received. The ability to create mods to polish the interface to sleek perfection is another thing. WoW already has this. I also think players should be able to host their own events in the MMO world, as well as create their own PvP maps or random PvE occurrences. This doesn't solve the raiding issue directly, but it would allow SE to have a treasure trove of content without even devoting some of their resources to creating said content. Players will do it for free, because certain players have a passion for creating these things. In return people have a ton of things to do. Furthermore, being able to host events as a player would truly put the RPG back in MMORPG. The key to implementing this while still retaining the progression is to only offer cosmetic rewards in the player created content, never the official rewards that would have increased stats. People would dabble in these things to check them out, or for the fun of designing. Imagine the amount of outfits and avatar skins if this was implemented. Not a single player would look the same as the other.
I don't think this is possible to implement in FFXIV at this point, but that's my idea for innovation in the MMORPG genre as a whole. To give players some power to create for themselves.
