I use Jump when Power Surge is off cooldown as a combo bonus with a Life Surge Full Thrust (They both share the same cooldown so it's good to pair them.) And I will use jump OFF That cooldown if I need an extra burst for a DPS check.

Dragonfire Dive and Spineshatter dive are gap closers, Dragonfire dive used as a priority when I should not stun or there are multiple DPS targets in range. (Also use it on gathered trash.)

Elusive Jump I used either to close or gain gaps depending on circumstance. It's a powerful maneuvering tool and hate drop (I can pull hate off my tanks if I'm not careful, so I use it as insurance.)
