After doing some research and number crunching, I noticed that probably the primary reason DRK's initial enmity generation outside of DAPS is weaker is because we have DS up from the get-go. WAR has to spend 3 GCDs putting up buffs and PLD doesn't wanna waste its buff on Halone at all, so they both get 3370ish potency from an initial enmity combo opener, whereas ours (a base 2955 potency) is actually 3546 since our DPS passive (Darkside) is up 24/7.
