It's about time to add Coil story mode, isn't it ?

[Ooshima]

The story in coil is a large part of the reward of clearing coil

The gear is just a means to an end, and a reason to keep running it after completion.

The problem I've noticed with most PF/DF parties is that there is no communication before starting the fight, no real communication after wipes (usually nothing or aggresiveness). The party should run through strats before to ensure everyone is on the same page. After wipes discuss what went wrong and how to improve.

Without communication, things will fail.

Then can you explain why does primals have story mode then?

Story isn't a reward - in a RPG game especially, story is actually quite the core, and coil (and CT/ST) actually tells us more about what happen to the Allagans and of course, the transition from 1.X to 2.X. It is especially more important for newer players, and of course non-legacy players. With the move to 3.X next year, there is a lot more lore in FFXIV. Asking the new player to play through them takes a lot of time which isn't necessary as players should be enjoying the latest contents possible. This is a natural point of view as a developer and of course, Yoshida see it this way.
