The treatment MCH, BRD, and DNC got for Troubadour, Tactician and Shield Samba was a move in the right direction for job identity. All three skills do the exact same thing and would qualify as Role Skill material but having them visually distinct adds to the overall feel/class fantasy.
I understand it would be an undertaking to create new animations for each skill but it would add much needed flavor to each job. Several could simply be reverted to previous skills/animations - such as Leeches/Esuna/Exalted Detriment.
Another example: Reprisal could stay as is for DRK while bringing Flash back for PLD (minus the blind but instead apply Reprisal's debuff). Flash is still in the Lorebook as a core PLD skill but has been removed entirely from the game - this could help to rectify that. WAR/GNB would gain visually appropriate versions as well.
