BLM, RDM, BLU, SCH, or GEO.
Abyssea La Theine, regen atma (Mounted Champion, Stronghold) and refresh (Minikin Monstrosity) at conflux #5 vs. Puks.
Gear up just enough Magic Attack Bonus/Magic Damage to deal 500-600 damage with AoE spells like Sandspin or Stonega etc, the rest -DT. When their health gets too low use a wind spell like Aeroga or Subduction and raise their health back to full. Rinse and repeat until 50k sparks.
I preferred to do it on BLU/RDM using Sandspin and Subduction, making use of Phalanx, Protect III and Shell II.
As for melee, 1H jobs like THF, NIN, MNK etc. do well at Abyssea Tahrongi Conflux #8 vs. Qutrubs. Just set Razed Ruins and/or Gnarled Horn, and Apocalypse.
