So she barely plays the main story, treats the game as a visual novel and ignores all the content out there that requires you to actually press a few buttons, and then complains there is a lack of content? Well yeah, if you ignore 90% of the menu, even though everything is getting catered to casuals at this point - even savage raids and ultimates - there is indeed nothing to do... To open that person's eyes.
They get everything on a silver platter, ruin the game's part of the game because Square is bleeding money outside of XIV and need to cater to the whiners, and they still manage to whine.
