Looking for a bit of feedback for Ast and dps

[Troile]

I wish there was a chat feature for this since i don't feel this needs a whole post related to it. At any rate I'm currently a level 59 AST roughly in the 130s for ilvl. Running dungeons like the vault I'm being told by others that my dps is laughably low (not in rude ways) outside of gravity spam on multiple enemies.

I don't have a way to check my dps of course, however it's a huge mana drain to deal damage in these dungeons especially because I also end up healing pretty constantly. I'm wondering if it's even worth it to attack at all.

Basically using diurnal i start with aspected bene and helios then a second of collective unconscious, then switch to cleric stance. In cleric i apply the two dots then proceed to malefic 2/gravity (i apply card effects etc).

If i resort to gravity i guess im doing decent damage if there are multiple enemies, but i wonder if it isnt better to save the mp for healing.

What is the general consensus for ast? Does every little bit of damage count and I should just make sure to use LA, lightspeed, and ewers to make sure i have enough mp to heal? Or should I only heal unless it's absolutely safe to dps? What do you other Asts generally do?

Just for reference, I dont feel like a dungeon like the vault is especially difficult to heal outside the final boss. However once i get to him the only time i feel i can deal damage is the orb phase.. otherwise I'm full time healing. Is this what you all did at my ilvl here?
