Maybe I'm missing the point of the OP...., but I find it difficult to see what FFXIV has failed to do.
1. Amazing story spanning 10 years. Check.
2. Engaging combat that can be incredibly deep. Optimizing rotations and lining up buffs.
3. Good Savage tier. And going back to the old savage with min iLevel.
4. Decent attempt at PvP that has been lacking for years. I'm having a blast with CC atm.
5. A literal Plethora of things to do that offer: mounts, glamour, titles, gear, etc, etc.
6. I decent housing system, while I don't engage in that. It seems people are doing incredible things with housing. The hub ub of the recent lottery has some large reason for contention. While I know people that were affected by this, I don't think it's worthy of threatening remarks. It's a game...remember that. This will be addressed and mitigated as best it can be. Mistakes happen.
Personally.
This game is not dumbed down at all. I have been fully engaged with savage this tier. And working with my team to preform better each time. We even made a pact to do endsinger completely blind with no guides....and having a BLAST...and made it to quadro planets the first night...so much fun. Laughing until nearly in tears at people getting thrown off the edges.
Crafting is still engaging for me, and making tons of GIL. Gathering this expansion is MUCH more engaging with actually needing to meld/BiS for high level mats.
Having a blast in Crystaline conflict! This is the most PvP I have done in ANY MMO, even more then WoW, of which I did enjoy also. Can it be tweaked? Sure. Is it something that I should be flipping a table over. Absolutely not.
Maybe I have mellowed with age (38), but I do not take this game to seriously. I understand it's a game and simply there to be an escape to my stressful life.
I however want to encourage SE to keep up the work, and to emphasize Rome wasn't built in a day, and that it took even longer to paint it. Don't dwell on the setbacks....play the objective!
