The suggested reasons for removing GNB/DRK jump were always incredibly weak. If they wanted to remove it from the basic rotation, just make it do no damage. Jumping on your target and doing 0 damage doesn't seem any weirder than Reprisal's 0 damage "stab your target and rip it out" debuff animation.

However, if damage was still super important to keep for these skills in particular, the alternative solution: keep GNB/DRK's jump with the potency, and simply make it unusable if you are too close to your target. It can function as an intended gap-closer, but running away from the boss to get the distance to use it again should be a DPS loss, and therefore not viable for rotations anymore.

I am sure the devs could have considered this solution. That they went ahead anyway and put resources to making inferior looking/sounding abilities, with worse animations, and less appropriate class theming, has me wondering if it wasn't a dev's personal pet project or something.
