WHM might be meta

[winsock]

The fairest exchange (both jobs each with their respective bis gear) has whm doing 17.59% more than scholar. As we are going early into the expansion, the numbers should be closer to how they are with no gear, so white mage will probably outdps scholar by a fair amount in the early tier(s) of savage. Once we get actual numbers, this is going to be way more accurate. But for the sake of argument, let’s say whm does about 30% more dps than scholar

^ you're making a HUGE assumption here.
We dont know exactly what the potencies are. SE has stated WHM is 'pure healer'. The current DPS requirements for SSS only require the WHM to push roughly 5% more than SCH. You're estimating the "fairest exchange" being a WHM lead around 17.59%, then bumping WHM up to a whopping 30% lead. I would wager you are overestimating the WHM lead by a substantial amount.

Let's also not forget if SCH and WHM are both in full DPS rotation, SCH can offer a great deal of support without interruption. It is a pretty significant chunk of DPS lost just for the WHM to maintain Regen on the MT. SCH also takes less of a penalty to dps if it needs to move for a mechanic, etc

While it would be great if WHM could make it into the meta, I am certainly not holding my breath.
