LAe'Zel at least can jump farther than my rogue. What interests me is if the movement consumption is based on the action itself, so that a jump always deducts 30% or so, or if it does so proportionally to the jumping range. In the former case, always doing a jump could make you move further in every turn when giving up your bonus action.
Not just Lae'zel, any Fighter can jump the same distance as her.
I beleive it is complete Strength basis to jump, Dexterity might be related to movement speed though
