The calculated armor value for raid bosses throughout Mists of Pandaria is 24,835, which when reduced to 21,855 (by the 12% armor debuff) amounts to about 32% armor mitigation versus a level-90 player. Unless mitigation from armor for bosses in WoD is significantly lower than that of their MoP counterparts, Flaming Shots is an increase in autoattack damage of 17.6%. If the armor debuff is not on the boss, Flaming Shots gets even better.
This is all before SV mastery even comes into play.
