Hybrid Slot, Assault Radial vs. Core

[lurker13]

First off, thanks for responding on a three-year old thread.  It's a testament to an engaged and helpful community.   Truly CoH-worthy.

This is for a Guardian Hellfire/Dark build.  This AT is on Rebirth so might be called something different (if even present) on HC or other servers.    Many powers have a minor toxic DoT.  The set's tier 9 is an extreme fire DoT.  Also have Soul Storm's moderate negative DoT.  Res debuf abounds.  Procs are present but not as many as I would prefer given all the DoTing.   I chose to pursue some higher set bonuses in this particular build.

I think your "it is activating an attack that adds a stack or checks for DH" answers the question.  I mistakenly thought otherwise.  Appreciate the concise insight.
