Unlikely as they already proved they cannot split challenges on faction type as seen with the HB debacle.
Weren't all of November's challenges faction-based? 300 Darkspawn, Qunari, Venatori, etc.
I'm expecting something equally accessible for all player types again. They essentially gave away endgame loot with the challenges in November, so I don't see why they wouldn't repeat that for the next month in an effort to put the few active and newer players on a similar playing field before support ends. One last opportunity for lesser geared players to catch up with the rest and finally rewarding those players who put in all the time but don't have the gear to show for it...makes sense to me.
