A quick comparison of "Emergency Buttons"

WHM = Benediction
SCH = Lustrate
AST = Essential Dignity

All of those are similar, so each job has that base covered.

WHM = Asylum
SCH = Sacred Soil
AST = Collective Unconsciousness

Again, all similar. Clearly the whm wins out on this one, but all these abilities are more situational than emergency.

WHM = Assize
SCH = Indomitability
AST = Celestial Opposition

The AST ability is definitely weaker than the other two, along with a longer cooldown, when it comes to healing, but the duration extension can be useful if timers are running down, and you don't have time to refresh aspected benific/helios not to mention the card buffs. I would be alright with them adding an aoe heal to this or working it in with the sects (didn't they mention something about this?) But all these abilities are similar once again.

WHM = Presence of Mind, Tetragrammaton, Divine Seal(I personally don't consider this an emergency button cause im using it on cd, with discretion)
SCH = Emergency Tactics, Dissipation.
AST = Lightspeed, Synastry, Time Dilation(although not a heal spell it does increase regens and buffs and can be used in a pinch to save time refreshing them) The reason I mention it, is because it could be altered to have an additional effect depending on stance.

Obviously the WHM wins out, but of the 3 it is the only "pure" healer. And all 3 are capable in the right hands, or fail in the wrong hands. Selene my bring A guaranteed buff, but she does not much the diversity of the buffing power that AST brings to the table period, and said buffs although random, are all helpful. Do I see a bit more help coming the AST way, most likely yes, Is it anywhere near the doom, gloom and misinformation posted about it, no.

I think the biggest help to AST would be to increase the range on helios, aspected helios and the card buffs, there is no reason they should be that short ranged. I am also wondering today if they got the sects wrong, and that diurnal should have the 5%percent potency buff, and Nocturnal could have something else. (seriously, if the shields wont stack with SCH make them work like SCH and add 5% crit.)

All that aside, Astrologions are great, and I enjoy all the posts about what people like about them, keep it coming.
