The posts that are bellyaching about the spec don’t have contention with the design, for the most part, but rather the damage. This double attack talent would serve as a flavorful callback to a former talent the specialization had and a buff to damage without conflicting with the streamlined philosophy of Midnight. Could give it a unique punchy sound effect when it procs for a dopamine hit.
Went to go take a look at Slayer’s Dominance because I could’ve sworn it specified that it procced from ability damage. It simply says that attacks against the primary target have a 15% chance to trigger it. If it does just proc from ability damage, then Double Attack would be distinct and complementary to Slayer’s Strike. If, instead, it does proc from melee attacks then this hypothetical talent would synergize with it.
I would hop in game to test but as of the latest update I’m getting a fatal error.
