Low Berserk animation displays when the dark knight is at full HP

Description of the bug: (optional screenshot/video): Sometimes, when a dark knight is above the HP threshold (viz. >50% HP) that the Berserk animation is supposed to display at, the animation shows anyways. This appears to be client-sided, as I believe I’m the only one who can see it. Here’s a simple demonstration:



What is supposed to happen?: No Berserk animation is supposed to display from anyone’s perspective
Where did you find and/or notice this bug?: On my dark knight IGN rusa.
A step-by-step guide to re-producing this bug (optional): Not sure. Seems to happen more if I come out of the Cash Shop.
Extra information (optional):

 

Quoting the balance changes:

Plus, even if you were right, and the Berserk animation were intended to always display regardless of the DK’s HP, this is still a bug, for two reasons: (1.) the animation sometimes — but not always! — displays only for the DK, i.e. other third parties cannot see it, and (2.) the animation frequently does not display at all (even from a first-person perspective).
