Since 4 years is not enough to allow me more than 1000 characters, cont'd from above:

I agree that WHM's design seems clunky in comparison to Jobs that were just built from the ground up for level 70. That's the way the cookie crumbles, and it applies as much to DRG, NIN, and poor, poor SMN. You could take away all of WHM's 62+ abilities and it would have a fairly minor impact on its efficacy and gameplay. And nobody would miss any of those spell effects, would they? I think that's what the widespread "meh" that 4.0's WHM has received boils down to. It's still 3.xx WHM, and people want new things from expansions.
