You also forgot that WHM will not be able to uphold that DPS (which it desperately needs to be even semi-relevant) as soon as we have to move. SCH is better in that discipline and AST blows both of them out of the water. So, unless we get many fights where we can just stand around and DPS, WHM will fall behind pretty quickly... again. And then there is the very likely possibility of early buffs, which will completely ignore WHM and benefit the other two healers like in Stormblood... we all know how the story ends.
