Currently now the game rewards player with first Victory rewards in lower dungeons but once level 50 there is no such rewards. First time victory rewards give players with exp and gil based on how many players have not obtained their first Victory in the dungeon or primal fight yet in dungeons and primal fights not lvl 50.
At lvl 50 there is no such rewards it is just simple win and get something. There is no incentive to help players learn how to play through the dungeons or primal HM since people are rushing endgame.
the dungeons and Trails we have from lvl 15 to lvl 49 completion rewards are First time Victory rewards. The size of rewards is only measured by how many players have not obtained their first victory yet.
