The biggest problem I have with the game right now is that it tend to try and appeal to as many people as possible, without the means and the creativity to do so.

- It wants to be a leveling MMO, when leveling, after the first job to 70, is quite dull because the rewards for leveling up are small, the leveling is way too fast for this type of game, and there is not a lot to do when leveling. Plus, the regions are far too small to make this a good leveling MMO. And with Eureka, the devs showed that they had no understanding of what makes this type of MMO fun.
- It wants to be a pvp mmo, but the battle system is absolutely not adapted for this kind of game, and the devs are trying way to hard to prevent it from dying.
- It wants to be a PVE mmo, which is fine since the battle system is great for it, but players will only receive 4 savage fights every 6 months, and two ultimate fight per expansion. Dungeons are just rollface for anyone with half a brain, and since their is so little to do PVE-wise, the difference in skill between players is really showing.
- The developers wants the players to socialise between them, but the game never really encourage you to play with others.

Honestly it's fine that they took after WoW for ARR, but they have clearly no idea where to go from there. They want to please everyone, but without any actual ressources to do it and really no creativity to make up for the lack of means.

To me, what's wrong with FFXIV, is that they're spreading so far to please everyone that they will end up, almost unironically, pleasing a somewhat niche group that enjoy a little of everything but never going to much in depth with it.

If S.E. wants to fix it, they will definitely needs to drop some type of content and focus on others, while they want to define where they want to go with FFXIV as a MMO.
