What perk? And again, it's not quite like FoH. 1) Tempest does not work as a panic button. -A) Not an immediate cast, Drains super over time. -B) No damage reduction while in super. -C) Damage isn't delivered in a wide spread like FoH. 2) Tempest only effects targets in your frontal cone of vision, not in the full area around you. 3) Tempest is not an instant kill effect, instead it deals high DPS over time when holding the Trigger down. 4) Tempest does not reach further distances than Shockwave. 5) Tempest does not leave a AoE effect after cast.
