So here are the raw stats put side by side (only comparing Diurnal with WHM)
HEALING
Benefic - 400 Potency
Cure - 400 Potency
= Equal
Helios - 300 Potency
Medica - 300 Potency
= Equal
Benefic II - 650 Potency
Cure II - 650 Potency
= Equal
Aspected Benefic - 240 Cure Potency
Medica II - 250 Cure Potency
= False (And I guess a 10y difference if you're a baby and care about that sort of thing, still doesn't change that this is false @Namo-guy)
???? - ????
Cure III - 550 Cure Potency AoE
= False
Essential Dignity - 400 Potency x Target Missing HP, 40s
Benediction - Restores all Target's HP, 300s
= Depends (do you want instant cap and longer CD, or more large chunk healing with lower CD)
Aspected Benefic - 190 + (140 * 6) = 1030 cure potency , 18s
Regen - 150 *7 = 1050 potency, 21s
= False (thank you for correction @File2ish @Sleigh @MidnightTundra)
Assize - 300 Potency cure to all party members, 300 DPS to all enemies, 10% of max MP restored
Celestial Opposition - Stuns all enemies in range for 4s, increase buffs by 5s
= False (grossly false at that...)
Collective Unconscious - 150 Cure Potency and damaged reduced by 10% (15s)
Asylum - 100 potency (24s)
= Depends (sure AST is stronger here, but it's less duration meaning you can't pop it too early, and it grounds you were as the other does not for less potency)
????? - ??????
Tetragrammaton = Cure Potency 700 (60s recast)
= False (kinda makes up for the benediction being 300 giving WHM 2 big "Oh No Buttons!")
I'm not going to touch the DPS side of things because that is it's own discussion but here lets go into abilities.
ABILITIES
Cards (and abilities relating, draw, shuffle, dilation, etc.) = Their own buffs
???? - ?????
= Better (yep card buffs do help, even if its very small and not very long it is a leg up.)
Synastry = 40% of a cure goes to someone you mark and increases potency by 20% for 20s
Divine Seal = Increases potency of all healing magic by 30% for 15s
= Depends (want 30% for all abilities for everybody lasting 15s, or want 40% of a cure to go to 1 person for 20s, both are beneficial)
Lightspeed = Reduces MP by 25% and cast times by 2.5s reducing magic attack potency by 25% for 10s
Presence of Mind = Increases Spell speed by 20% for 15s
= Depends (mp reduction and caped 2.5 off casting with a -25% dps penalty, or a scaling 20% that doesn't reduce MP cost doesn't reduce potency and lasts longer).
.... Oh and further more that isn't even the traits in which AST is grossly lacking compared to WHM.
TRAITS
Enhanced Light speed - decreases DPS penalty to 25% from 50% (shouldn't need a trait for what it should be)
Enhanced Medica - 20% Medica MP will b halved.
= False (I would much rather be conservative then given an ability I should have without the trait)
Enhanced Essential Dignity - 40s recast now (shouldn't need a trait for what it should be)
Quick Stoneskin - 2.5s cast time
= False (I would rather a faster shield then given a trait for what I should already have)
Enhanced Benefic - 15% chance Benefic II will be instant cast.
Freecure - 15% a Cure will make a Cure II Free.
= Depends (a Free cure 2 or a fast one, I would rather free, but fast is helpful in run and gun)
Enhancd Disable - Increase reduction to 10% (Shouldn't need a trait for what it should be)
Overcure - 15% chance your next Cure II will half the cost of your next Cure III
= False (I would rather a cheaper AoE cure option for conservation then an ability I should already have)
7 = FALSE that AST is better then WHM
5 = Depends both are pretty good but somewhat different from each other (essentially a draw but not equal)
2 = BETTER in which AST is technically better then a WHM
3 = EQUAL when AST and WHM are equal in every way.
Right here.... Most of the traits AST gets, are what the abilities should be anyway with out the need of traits making them more reasonable. That's like giving a kid a remote control car, with no wheels, and then on their next birthday giving them the wheels to put on the car.... Where as WHM have traits that enhance what they already have not giving you part of what it is and giving the rest later...
You seem to be recognized for being hard headed and not willing to listen, but I figured I would at least take the time to point out why it is you're wrong, and at least it will give me the access to point it out later when you make this silly claim that AST will replace WHM in some upside down world.
What this shows is that our abilities are slightly different and while AST is best with card buffs and Aspected benefic over Regen. AST is failing in having a 2nd "oh no" button cure, a multi purpose AoE ability (Assize vs C.O.), a third and strongest AoE heal at a stronger potency then the other 2....
We give a massive cure, multi purpose AoE ability, and a 3rd AoE heal..... for cards and a stronger single target regen heal..... Also we give up traits that enhance our classes efficiency for traits that give us the abilities we should already have and yet we are superior?....... You say we'll be replacing WHM how soon again?
I'm not writing this because I think AST should have what WHM has or should be better then WHM, I'm putting this hear because I disagree entirely with AST being better then any current healer, and claiming that it is even equal to the other healers is being far too kind and grossly misinformed... A great healer can make this class work, no doubt, but it would be better if it was actually put on an equal footing with the others rather then held back by it's major setbacks in the healing dept and lack of emphasis on the cards which are meant to make up for its lack of healing.
