Personally, I liked XI's DRG setup with the jumps ontop of jump enhancements. For example you go Jump > High Jump > Super Jump > Spirit/Soul Jump. The latter is enhanced by having your Wyvern present which always forced it to give a TP bonus. The Mythic for DRG forces criticals constantly which not only returns more TP but does quite a bit of damage per jump.

GB's enhanced Jump works somewhat like XI's, so since we can upgrade it maybe it'll gain more parameters for enhancing jump. Never know what SE has planned fully.
