The good news is there aren't any badges that require the usage of the Jump Pack in RV (all on the ground).
As for the rest of the PvP zones, they can be collected without the Jump Pack if you jump on the geometry of buildings, use any vertical-capable travel pool powers, or ask for assistance from someone with team tp (like the old days of badge collecting!). I would notch this one to a minor inconvenience, but note worthy for its impact nonetheless.
As for PvE content and zone-event activities in PvP zones, I am pretty familiar with each PvP zone and I can't think of a reason to need the Jump Pack. Sometimes I try to get on top of the Warburg rocket after I launch it, but I am never quick enough. What are your experiences?
