Been asking for one of these for years! Definitely agree. Even if it's not a gain in DPS, just the option and flavor would give the overall feel a boost I think. Something like Chi- or Air-Blast like they've gotten in previous titles. I also hope Chakra gets a rework so we can at least hold 2 Forbidden Chakra's worth at once, just to prevent overcapping. Right now it kinda sucks being in your opener and getting 5 stacks RIGHT as you're about to hit Bootshine. It's small but classes like WAR and NIN have the extra wiggle room to prevent that and they feel much better in that regard. I say that to also say having a little extra would allow us to fire off a few blasts while moving away from the boss. SSS is fine and works but it's no energy orb/beam.

Edit: Better yet, give us a disengage combo like Samurai have too.
I LOVE that about SAM, and MNK could use one too.
