If Barspells are generating too much enmity... surely the WHM AOE versions should also receive an enmity decrease? Or is WHM now intended to tank; what with barspells, and spamming cure V cureskin on themselves.

As for Utsusemi: This will also reduce the enmity of any DDs/mages going /NIN, so it's not all bad. They should have left the nukes and enfeebles alone though.
