I see where you're coming from but Provoke has been known by many different names in the FF series: Provoke, Lure, Decoy, Taunt, Challenge, and Draw Attacks. All of the names let you know what they do and at the same time they have subtle differences that could be made meaningful for job flavor.
PLD could Challenge with its roots as a GLA in the Colosseum. WAR could Provoke for series continuity and a nod to the characters in the job story. DRK could Lure as it does with criminals in its story. GNB could Taunt as a nod to the Squall/Seifer relationship.
It's like how the healers have the identical-in-function-but-different-in-animation: Raise, Resurrect and Ascend. They all are simply referred to as "Rez/Res" and it's understood what is being requested (nobody asks an AST for an Ascend). Same deal would happen for "voke".
