I have heard both yes and no. Its pretty stupid that you can get 86 JPs from doing Cata 5 mans per boss but only like 36 from MoP heroic bosses. It makes getting BoAs such a pain in the ass. I have been forced to keep a character at 85 just to chain Cata instances for BoAs or use my main and do BGs all day long and convert honor to JPs. Also level 86/87s will purposely queue for Cata 5 mans just to troll you because if anyone is over 85 no one gets any JPs so even doing Cata instances doesnt always work. Please tell me they are increasing JPs that drop off of bosses or at least will let us convert Valor to JPs. If they are supposed to be making the game more casual friendly forcing people to grind longer cause bosses only drop half the JPs they did last expansion doesnt really accomplish that goal.
