You say you don't care about endgame, or raiding, and yet you want to participate in a storyline that takes place only within a certain raid dungeon. Why do you even care about what is going on within coil if you don't care about coil at all?
You are simply just another player who want's all of the rewards without any of the work that other players put in to receive them. No different then me saying I want to participate in all of the crafting class quests and stories but I don't want to actually spend the time and effort to level them up. They should totally put in an easy class quest system for all of the crafting and battle classes too, so I can see all of the story lines without having to do any work to see them.
That's basically exactly what you are asking for with coil story. I want to see all of the coil story and content, but I don't want to put in any of the effort that other players are in order to see it.
