Thoughts on Defiler?

Ive been thinking about trying a Defiler based on the Dracarris build, but I am not sure how viable that would be. Anyone else have any thoughts on such a build?

You’d have significantly more pets via skellies and stronger general pet bonuses for them, but no Hellfire or Storm Spirit means much less flat Fire damage to focus on, and less Fire resist reduction without CoF is big as well. My hunch is that it would be weaker.
