I can agree with the first bit. AST's power comes from a coordinated group taking full advantage of the power AST gives. As soon as you take things into a PuG setting when you can't guarntee the other 7 people will make use of the AST's tools, it certainly makes it less desirable in those scenarios. If even one person misses Star / CU, the AST will need to make up with that via Dignity and/or GCD heals. Though admittedly a lot of people talk about AST's strengths in the context of optimal play so..
I will disagree with the second bit unless they also give raid buffs to WHM as well. My reasoning is the fact that real DPS contribute a higher percentage of damage than healer DPS would. Even if gear scaling increases all player's DPS at the same magnitude, healers who contribute rDPS will get higher returns versus those who do not because the raw DPS increases will affect them more.
Here's an arbitrary example to visualize my thoughts:
ilvl 100
AST = 4,400 pDPS + 530 rDPS = 4,900 total DPS [Assume AST buffs contribute 1% more DPS for a group that does 53K total DPS]
WHM = 4,900 pDPS = 4,900 total DPS
ilvl 130 (assuming a +20% DPS increase)
AST = 5,280 pDPS + 636 rDPS = 5,916 total DPS [Assume AST buffs contribute 1% more DPS for a group that does 63.6K total DPS]
WHM = 5,880 pDPS = 5,880 total DPS
So with the above example, WHM and AST were equal on one tier but as soon as the next tier happens, WHM will start to fall behind. I feel this issue would be exasperated more if healer DPS was even further reduced and more emphasis was put on tank's and DPS' DPS.
Though again, if we give WHM some form of raid utility, that'll help bridge that potential gap and I'd be more inclined to agree with a healer DPS nerf.
Thanks for the insight~
I'd like to add that AST is also almost equal to SCH in pDPS contribution across the board as well. For a healer job that is suppose to have the least potential DPS based on SSS, that's also something that we shouldn't consider normal.
Funny enough, Aspected Benefic is actually more potency per 3 seconds than either Regen or Embrace when you combine both the initial heal and the the HoT component of it.
Regen = 150 potency / 3s
Embrace = (250 potency*0.66) = 165 potency / 3s
D.Aspected Benefic = {[200 + (140*6)]*1.1} / 6 = 190 potency / 3s
With that being said, given the GCD commodity game we play now for optimized play, I'd also be inclined to nerf Embrace. Both Regen and D.Aspected Benefic cost a GCD and AB also costs an arm and a leg to cast where as Embrace is both GCD and MP free.
It's amusing - I wouldn't of remotely thought of agreeing with this suggestion back in the second / final Coil days but times have changed a lot since then.
