So according to the census from February, there are slightly more whm and astros that are max level than sages and scholars. However, when accounting for ilvl in an October census, end game white mages and sages who have savage ilvl gear greatly outnumber astrologians and scholars with similar gear. Astrologian was actually kind of popular last tier.

Astro was actually kind of popular last tier when the healing checks were easier, primarily because it added much needed stimulation for some players. That being said, when the difficulty in healing spiked, apparently its extraneous features became a hindrance rather than a source of amusement. If they can get the scholar and astrologian toolkits on the same page as the white mage and sage, we're basically golden.
