The battle themes are fine in this game, especially things like the garuda theme, but the biggest problem with this games soundtrack aren't the works themselves, its the atmosphere they bring to the areas you are in. Listen to the pieces below from final fantasy XI and you will understand exactly what I mean.

Just listening to these pieces you can pretty much picture the areas that they represent, even if you have never played the game before. The ronfaure theme gives off a sort of medieval forest vibe, something that would be reminiscent of a robin hood tale, and the rolanberry fields theme is just sounds like it belongs in a peaceful meadow full of rolling hills. The Sanctuary of Zi'tah sounds like a desolate area thats been lost to time. These are just a few examples but you can pick out almost any piece from the ffxi ost and close your eyes and visualize an area similar to the one that it represents in ffxi even if you have never been there.
This is in extreme contrast with the ffxiv ost where if you were to listen to any of the pieces the average listener is either going to have trouble visualizing where the hell they belong or probably envision an area that is absolutely nothing like the area that it represents. That isn't to say the ffxiv ost is bad, its just incredibly out of place and doesn't add to the atmosphere of the area. Lets take thanalan for example, probably one of the best zone area themes in this game.

Close your eyes and listen to this, its incredibly gentle, yet intense at the same time. In my mind it portrays something incredibly grand, something beautiful like watching the sunset from a cliff over the sea, and once the sun goes down fireflies start popping up all around you and its just incredibly serene in general, yet when you walk out of uldah and that theme starts playing what the hell do you see? Nothing, its a barren freaking wasteland outside of uldah. Granted, yeah there are cliffs over the sea, but thats such a small portion of the zone as a whole that its not something that is going to define it. The thanalan theme at best would have been best represented in la noscea, but only once the sun were to start going down, kind of like a night time thing.
Next we can move on to the La noscea theme.

the first instruments you hear from it are something you would predominately expect to hear if you were watching 2 people try to cross a desert. And even though its added to with a beautiful orchestra that crappy beat that starts off in the first half a second persists throughout the entirety of the piece. La noscea is predominately a bunch of wind blow cliffs by the sea, the main orchestra kind of represents that "sea" feeling but the fact that that beat is in the background throughout the entirety of the piece completely ruins the atmosphere of the area as a whole.
The problem aren't the pieces themselves, its the fact that they weren't made to cater the areas they are supposed to add depth to.
