AST got buffed quite nicely. I tend to like Diurnal, but that's because I just prefer the AoE regen. Nocturnal is definitely viable though--they both get the job done. It's really just a matter of preference. Diurnal in full party with SCH, and Nocturnal with WHM is still accurate.

Cards got a nice little buff as well. Balance/Bole/Arrow/Ewer/Spire/Spear tends to be my priority order most times. Balance and Bole for obvious reasons. Arrow/Ewer/Spire are more situational and interchangeable depending on my party. Spear--I tend to use before I use Lightspeed, etc.
