I just stated "BiS" as a simple modifier that explains all gear from highest tier of raid content available. The mixture is indeed part coil gear and part soldiery (and mythology gear before it during 2.0~2.1). It was just a broad explanation of how they proceed to implement content. The fact that it's also a mixture lends itself to how fast the highest tier of raid gamers seem to quit within 3 months for a while too.
Sorry I did not make this more clear.
