well, but PP and DPP are skill criticals every time, not to mention with Phantom Crow 7 and Mortal 7(iirc 20% boost to PP/DPP?) these criticals are getting boosted more. And do not forget, while you might have more melee, Invenom is a by far more better imbue than Frozen or any other for that matter. Though a crit with Brandish Kick might exceed PP and DPP, the overall damage output is better on a Str Dhan.
