Shukuchi got a second charge simply to increase NIN's independent mobility to make it stand out. It doesn't need damage tied to it to qualify for a second charge, otherwise En Avant which starts at one charge would be a culprit as well.

The reason tanks and Monk have charges on their gapcloser has more to do with the fact that they don't have alternative mobility as the remaining jobs.

- Dragoon has multiple types of jumps + Elusive Jump for a free-directional 15-yalm lunge.
- Samurai and Warrior's gapcloser are tied to resource management in exchange for a shorter cooldown.
- Red Mage hangs out in range and lunges into melee distance for their combo. Even using CaC on cooldown they are more than mobile enough and their weaponskills have shorter recasts. Displacement depending on the cooldown alignment is often less favored to Engagement to allow more stable weaving, but in turn Displacement does more damage so it's fairly alright.

Even assuming a gapcloser would still have a single charge, that is kind of where gamesense comes into play. Do you hold your gapcloser for a while so you can zip right in after having to run out or do you use it on cooldown and use Sprint to get back and forth? Depending on the situation, holding the gapcloser has a greater benefit than using it on cooldown because it allows you to keep the global cooldown rolling.
