Guild Wars 2

Bug: After swimming all Herald Facets instantly reset on activation. This persists after leaving the underwater section until the Dragon Stance is un- and re-equipped or stances are swapped. Furthermore active Facets are not kept underwater as previously.

Result: unplayable and can be exploited for unlimited protection at no energy cost

Swap your underwater skill to Shiro/Mallyx or the bug fix is to auto-set standard underwater stances to Shiro/Mallyx through code.

While that might be a temporary fix, the issue itself needs to be adressed ASAP. Which also includes making the other legends available underwater.
