There are different words but most mean the same:
  • Most Effective Tactic Available
  • Most Effective Tactical Advantage
  • Most Effecient Tactic Available
  • and more
All center around the simple fact of using a composition with the highest gain for a fight, for FFXIV it's mostly the highest gain of rDPS, even if only a small percentile of the players could effeciently use the advantages of this specific composition.
