I'm pretty happy with the story and the direction it's taking. After completing coil, I kinda realized there are multiple stories going on that may intertwine at one point. I can't see it as se needing you to complete coil to see more story and I think the 2 stories (scions story and coil story) don't really complement each other just yet other than maybe some fan fiction. I'm not sure if se even intends to mix them up in some form but I think the coil story is far more interesting.
