It's also a Final Fantasy game, and it wouldn't be one if it wasn't heavily story driven
Then make it entertaining and engaging, as I said earlier, some other FF games had AMAZING story, that people replayed dozens of times if not more, because they are just THAT fun. FFXIV's story is not that. And yes that is my personal opinion.

Most other MMO's force you to play different classes on different characters.
WoW's story is not 30 days long, you can level from 1 to max in 3 or 4 days time, you cant compare both. In the time you level 10 classes in WoW, you go through a single MSQ in FF.
