Cost is a factor, and yes while they're not BiS for avoidance, I think the extra EH is worth it, however I will probably pick up leggaurds of lost hope for an avoidance set as there are some fights that seem like they'll need it.
I still don't think block is a huge factor for warriors in most circumstances, I don't think CotT(and surrounding boss mechanic changes) replaces any previous values/priorities for warriors. I can see it for pallies since with holy shield they were getting unhittable and pushing block off the table, now block isn't pushed off the table and thus has more value than before, but I still think block is a tertiary stat.
