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

[EdwinLi]

There really isn't much story in coil its mainly there to be the end game raid to fight bosses and get loot.

Only if you skip or ignore the cutscenes. The entire story of Binding Coil is to explain what happened to Bahamut after end of the era trailer, what happened to Louisoix, and to also explain how Bahamut returns in FF14ARR which once he has returned Bahamut will serve as a Major Antagonist in FF14ARR once again.
