I'm not asking for any kits to be changed or added to from what each job currently has available. Every tank would still have a Rampart skill but for DRK it would be Shadowskin in name and animation, PLD would get back Rampart in name and animation, WAR could have an animation where they encase themselves in stone, GNB could have an animation utilizing their bullets.
Basically when every job in a role has the same exact abilities visually, it adds to watering them down. Balance-wise all of the role skills would stay available to their respective jobs - but they would do so under new names and animations that were appropriate for each job's flavor/lore/identity.
