I don't have it anymore hence the past tense "had data" or yes I would have gladly shared it with you. Lost the hard drive it was saved on due to it deciding not to live anymore and since I am lame I didn't have a backup.
I was around at launch and leveled both AST and WHM to 60 before they unlocked Gordias Savage and while AST was still viable it was way more difficult to heal on and the SCH + AST combo my boyfriend and I were trying to manage at he time while progressing Gordias Savage was just frustratingly worse than WHM and SCH even though AST was supposed to be able to pair with either healer.
I attribute it to the fact that AST and SCH gets no party MND buff and it lowers both healers heals even more and lowers DPS.
ASTs regens were also lower (Aspected Benefic Regen was only 100 potency at launch. Later on they changed it to 140) and the fact that Collective Unconscious regen only worked if you channeled the bubble (and couldnt cast anything else) made it mostly useless for most things while WHM had Asylum that you could from a distance safely cast over the tanks whenever it was up.
Synastry had no healing potency buff on it so AST essentially had no Divine Seal all while having worse base healing potency than WHM already.
Lightspeed still made you instant cast but it cut all damage
and healing output by 25% while in effect and did not reduce MP cost (they added that later and changed it so only damage is reduced).
The numbers didn't lie :x AST was extremely lacking in healing to the point where I was solo healing A1S Faust from 100% to 50% while my boyfriend on SCH only DPS'd then started healing at 50%. At the end of the fight he on SCH did double my healing even though he only healed for half the fight and I healed for pretty much all of it minus a bit of opener DPS.
I am not like super awesome best player or anything, but I don't suck really bad and I've been competent enough to clear almost all raids so far even if not close to world first etc.so skill is some of the factor since I am not a top tier world first player, but even with the skill I do have it was overly frustrating and stressful trying to heal with such low output compared to WHM and SCH.
