Those people exist. The game should not pander to them, or be changed to suit them better. That kind of people is not who I would want to attract to FFXIV though. As long as they are a small minority they are not much of a problem, but too many of them and things will start to change to accomodate them, and that would be a bad thing.
People who don't care about the story are perfectly welcome to play some other game that suits them better.
