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

[Kaelah]

People need to stop and think for a moment what they're asking for.
I mean really think about it.

Take a look at the level of difficulty in Leviathan/Ramuh hard vs the "other" hard mode primals. Then take a look at all of their extreme counterparts.
The number of mechanics used in Leviathan and Ramuh hard are ridiculous by comparison, almost none are used. They do not teach you much about their mechanics at all on your average first run through them. They even use less mechanics than Ifrit, Garuda, Titan, or Moogle. They teach you almost nothing.

While I do agree with your point, it could also be argued that if the primals have these "easy mode" versions that are easy to beat and teach us nothing of the extreme version, why can't Coil have the same thing? Just for story purposes.
