Ascendant's "Deadeye" ascendancy does not grant a frenzy charge every 3 seconds while moving

Looks like a bug that is here for some time already as can be seen here:

We're talking about "Gain a Frenzy Charge every 3 seconds while Moving" part

It's not, that it doesn't do that, yet the problem is most likely the "while Moving" part. Seems like constant movement doesn't count as "Moving". You also need to avoid colliding with a single thing, even though it doesn't stop the motion. Therefore a "movement" that lasts for at least 3 seconds is almost impossible to achieve under normal circumstances. Practically speaking - forget about getting frenzy charges from the ascendancy (at least in combat).

If we could get a fix, I would be most grateful.

(also a warning for those, who pick the ascendancy for frenzy charges until it's fixed)
