So just for fun a suggestion to change it so that instead of draining energy each cycle it causes a random condition IF the target standing in Chaos Storm is suffering from a hex.
The recharge, energy, casting time would be tweaked of course to balance.
Currently if I want to drain energy from a caster, I'd use power leak over Chaos Storm. Power Leak is precision in a box. Chaos Storm is negligible damage masking easy to avoid DOT e-denial on casters.
Hopefully at some point Chaos Storm gets tweaked.
It once was PVE useful when AI didn't scatter. Not sure if many people bother with it in PVP now.
Changing the spell to something similar to the suggestion at the top would get Chaos Storm to see some creative action again.

It would synergize well with epidemic and hypochondriac.
It would suit it's uber name better. What an uber name! LOL
