I'm really not going to argue over this. The entire, "BiS is BiS, period" from me was referring to that post that had been deleted. Obviously there are going to be some pieces that are clearly BiS, and others where you're unable to say, without a shadow of a doubt/proof/whatever, which is better. This is someones BiS list, and the deleted post was saying to include an item that had less armor, which made it not BiS. That led to my "BiS is BiS, period" comment.
Ofc stat weights are important, and I never implied otherwise. I also never said that BiS means only one piece of gear as there are often similarly good items with different stat weights. On the same note, there are pieces which are obviously BiS. Which still means that BiS is BiS for those clearly defined pieces. I'm done with this discussion though as my words are being misinterpreted into something I wasn't saying. I poorly word/phrase things sometimes, so it's my own error I suppose.
