Same as above, I don't think it would change anything about the rotation being strict.

If anything:
  • Dash shouldn't inflict damage but at most a debuff
  • Continuation shouldn't drop after another GCD
  • Sonic Break should be updated/merged
  • Blasting Zone CD should scale on skillspeed, it drifts very easily
  • Gnashing fang combo could grant a self defense buff to reduce the APM when a tank buster happens in a 60s window
  • Rampart and Camouflage could be merged, the latter is a bit niche

If anything, I'd also add a way for GNB to generate cartridges during downtime, something close to Umbral soul
