I do not want to see the Astrologian turn into the SE version of a wow restore druid. Nocturnal being pushed to be a more offensive stance that does not hurt the healing strength of the astro imo would be a more viable method. SE is not looking to totally redo an entire job toolkit at this stage of the game. Either find ways to make the stance work with only tweaks or wait til 4.0 most likely. I saw lots of raids in 2.0 Coils and extremes make use of double white mage quite well. Barely anyone used double scholar but no one complained to much about not being able to pair two scholars. Should not be a problem with scholar being almost irreplaceable for the time being to make up for being screwed over in 2.0.
