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

FWIW, I recently picked up AST and leveled it to 60, learning some of these things along the way.

Spell speed boost from Diurnal is VERY noticeable, and in general, I feel like I get a lot more mileage from the Regen effects than the Nocturnal shields.

By the way, there's a cool trick I picked up in this very forum that can be used at Level 60 to completely trivialize dungeon healing. It helped me realize AST's identity as the "regen healer," next to WHM's "burst healer" and SCH's "shield healer. Give it a try once you've unlocked the relevant abilities!

It looks something like: Collective Unconscious -> Synastry -> Aspected Benefic -> Lightspeed -> Aspected Helios -> Time Dilation -> Celestial Opposition

That might not make sense to you quite yet, but with this sequence, you can give the tank 3 suped-up Regen effects ticking simultaneously for 20 to 40 seconds each. You can then switch to Cleric Stance and DPS for days. You could also slide in a card, like Expanded Balance, before Time Dilation to give a damage boost to the whole party and just completely wreck dungeon pulls.

I haven't used my AST much in harder lvl 60 content, but I imagine this would be pretty wasteful in that setting.
