I am new to Astrologian, which stance is best for solo healing?

[GeekMatt]

I wrote up a guide on AST Sects on FFXIVRealm with a great pun in the title that if I type here may get me banned.

Noct is a powerful stance, and I wouldn't trust your friends math. However, Diurnal is always viable (unless there's another AST in that stance) and since Diurnal offers better MP management and better DPS it's hard to justify using Noct. However, there are certain fights where I feel that Noct is more powerful as far as strictly healing. It's what I used back when I first started solo healing Rav EX—with the hard hits and long pauses between the serious blows, shields really shine over regens.

Also, if you're aware of what's going on around you instant shields are godly. Anyone that says you can't heal stupid hasn't farmed Rav EX in DF with a good Noct AST.
