I honestly don't get the argument 'it's beta, it's a new game etc'.
These are design choices, they aren't falling out of the sky.

They could have added a few more things

- Zones with mobs that require a part to farm, they drop items/gil etc.
Give a decent amount of exp and are challenging.

- Daily instance/8 man quest

- Guildhests being weekly or daily and make them more rewarding

- Instances drop more gil

- Reduce fate exp

- Increase exp on killing mobs

- Job change is reset all quests

- Make a hardmode version of some lower level instances at 50 and rework loot.
This is cheaper than designing a whole new instance, you can adjust boss mechanics.


Again this is about making choices, it has nothing to do with it being new.
The fate grind isn't something you over look by accident.
