I checked all the blue-posts I found on this topic and did not find a statement that they are replacing the valor points for boss-kills in the current 359 raids with justice points.
Does that mean they will still drop valor points? So even if my guild is not very successful in the fireland raids, we could run the "old" and highly nerfed cata raids to hit the weekly valor point cap, getting 365 gear from the vendor? Furthermore: Never running hero dungeons again?
