I’ve always thought having a “TP Shift” ability on a healer or caster would be nice to have, since the resource isn’t being used. Same for a Mana Shift-esque skill on physical DPS that never use their MP reserve (won’t work on BRD however—we use our MP!). May not be used that often though, because TP is usually a non-issue outside of extremely heavy AOE damage dealing. As for TP mechanics, I’m not sure if the developers would ever give all healers abilities that use TP—any TP usage on a healer would probably be more for a singular job concept (like DNC).
