Raw Data:
I was checking FFLogs to see if the defensive buffs for DRK indirectly increased its DPS when I came across this "wonderful" finding:
https://www.fflogs.com/statistics/21...gregate=amount
AST is now averaging about 40 DPS more than WHM in the 90th percentile. At the 75th percentile, the pDPS of both classes is about the same. Note that this is NOT raid DPS, only personal DPS.
Let's compare this to patch 4.2:
https://www.fflogs.com/statistics/21...gregate=amount
By removing clipping and MP issues, the QoL buffs for AST have made it gain about ~350 DPS since last week at 90th percentile. IIRC, AST cards add around 300-350 DPS to the raid with Balance @ 10%, so this QoL buff ends up giving roughly the same rDPS gain for AST as if they made Balance 20% again.
Personal Thoughts:
Although these QoL buffs were necessary and have made the feel of AST considerably better, I was wary that they would indirectly increase AST pDPS to the point where WHM might look a bit less appealing than before. However, even my skeptical mind was not expecting such a large pDPS increase. I'm 99.99% sure SE did not intend for these buffs to be more than a negligible DPS increase for AST, seeing that even experienced AST players weren't expecting it either. However, here we are.
We're only a few days into 4.3 as of this posting, and the data may be an anomaly (although we have a fair number of samples to go with), but what I'm seeing is incredibly worrying. With these numbers, WHM are very likely to see a repeat of the 3.3-3.4 fiasco (although hopefully not as bad), as they now bring hundreds less rDPS compared to their counterparts, and their healing contribution is not as dominant as people think:

We haven't really seen the 3.3 dynamic unfold yet, thankfully, but logs are still stabilizing and public perception changes gradually after a patch. As more statics start figuring this out and reporting it, the information will trickle down to the masses over the next few weeks. Call me pessimistic, but I hope salt mages enjoyed late HW, because winter is coming.
The thing is that, if we use SCH as a benchmark, AST is actually right about where we expect its rDPS to be to keep things balanced, and I personally applaud the AST buffs. It's just that, given these numbers, WHM pDPS is massively, OBJECTIVELY, and UNDENIABLY undertuned right now. I say that for two major reasons:
1) WHM brings no raid damage buffs. SE's stated -- or heavily implied -- intention is that it is supposed to bring the highest pDPS to compensate. It is now the lowest pDPS.
2) Phenomenon #1 is due to the fact that, since 4.0, the other two healers have now received significant buffs to their DPS, while WHM has seen no potency buffs in kind. I like to call this the "Red Mage phenomenon", for obvious reasons.
Honestly, WHM needs about 300-350 more DPS, and even then its net rDPS will likely be slightly less than its competitors, compensated by its relative safety in comparison. I haven't crunched the numbers, but we're probably looking at around a 20 potency increase to Stone IV and a 10 potency increase to the Aero II DoT (NOT Aero III) at a minimum.
Optimally, these changes should come before 4.4, and hopefully even before 4.35. However, I've been a WHM since around 2.0, and I'm way too experienced with SE balancing to realistically expect that. It's entirely possible we might not even see anything significant before 5.0 if history serves us well. As a WHM main, I can say that I am NOT a happy camper right now.
