Also, if double darkness is part of your plan, say for bursting Death, plenty of melee reliably tp fast enough to open (1) and close (3) a three-step skillchain. There's still no justification for a third melee, or second if you can use the tank like Rudra's Storm > Requeiscat > Rudra's Storm, Shoha > Requiescat > Rana, or Savage Blade > Chant du Cygne > Requiescat.
