with multiple targets like how it is in alex savage, sch wouldn't be running on a rotation of energy drain spam. Although it would be very amusing to see a whm beat a sch on heavy trash mob pulls because I think it's:

assize/aero3/holy(with or without pom) vs bane/miasma2/shadowflare/blizzard2

The example in a2 follows with vuln up stacks which supports sch aoe dps more than whm in my opinion.
