The only things keeping XIV from being perfect to me are:

1. The ToS enforcement is pure trash and people can get away with both harassment and cheating regularly.

2. Virtually no mid/hardcore content for small groups. The later floors of PotD/HoH are basically the only semi-difficult four player content in the game.

3. PvP is...hit or miss. Some people seem to enjoy it, but for a lot of others the only thing that pushes them to get involved are the rewards which causes problems when said rewards don't even necessarily require a win to be obtained.
