It really sucks. I am another one that was REALLY looking forward to Astrologian.
Heck, I love how the class looks and plays...
I am trying to decide whether I want to stick with it to 60, or level another healer now.
I have scholar at 55, Astrologian at 41 and am considering trying white mage for a while.
AST are just so much more fun than Sch and Whm to me

.
I just dunno if I am willing to just trust that they will get them up there with Whm and Sch.
Kinda sucks if one healer will just always be inherently worse and a burden in comparison to your team.....
