Because FF14 is a terrible MMORPG.

If you understand MMORPGs, and go in expecting an MMORPG then you're going to be disappointed.

It is a single player game with average multiplayer elements.

Unfortunately, Final Fantasy fans had a bit of a cry when they realised that the original FF14 was a good MMORPG (as it borrowed heavily from FFXI) and, sadly, Square didn't want to drown under the salty tears of the whiners.

If you don't like the experience now (with the questing), you're never going to like it. There are plenty of actual, proper MMORPGs out there to try.
