Let's make WHM broken with instant cast Holy that is completely free due to Thin Air, which is crazy OP in it's own right.
Let's also make Aero 3 into an AoE draw in so that all enemies are pulled towards the targetted enemy so we can hit everyone with Holy better.
Finally, let's reduce the CD of Benediction to 1 second and make it an AoE instant cast ability.

SCREW THE RULES, I HAVE A WHM.
