Sirens get bonus Elemental Effect chance but Explosive weapons appear to ignore "chance" and always deal explosive damage. None of the Siren's skills appear to (directly) effect explosives.
Is there any benefit for Sirens when using Explosive weapons? In Borderlands 1 Sirens' "elemental effect chance" actually improved your "proc pool" which meant you could deal more damaging procs more often, which included Explosive effects. Is that still the case?
