I have no interest in crunching numbers or comparing semi-serious me vs batches of logs from the pros in top-content, given such exploration leads to the lesser-played portion when you consider the game as a whole. I may never see Kefka-Savage, so how I stock up vs 360-370il WHM in top-tier content as a semi-casual 356il won't matter so much - but even from the little I do see, I know I'm far from incapable of producing solid damage numbers, and the AoE is just gross. Yes, SCH isn't far behind in that regard, yet they also aren't producing AoE stuns alongside it, and (for all I know) may not share the same MP freedom, which means you can do more than required. Having said that, I consciously avoid SCH and AST - I have no desire to play them, thus I can't talk about them in any way.
Ultimately, WHM is in a good place right now - not amazing, far from terrible. People like me can live with being dungeon-centric and certainly don't see the need for further damage increases, especially considering how easy it is to provide what we are currently capable of. I'll leave the nit-picking to those who are actually effected by top-tier metas that may decide to exclude them due to their chosen class, yet I have a feeling (due to SE's supposed attitude towards DPS/Healing) that not much will change, regardless of the community consensus. Given our pure-healing status, I'm happy to see that we're at least, on average, the middle-road DPS. Throwing more on-top of it doesn't really solve much, as in curing one issue, you then highlight something wrong with another. The gap between AST and SCH already looks pretty gruesome.
