[BUG] Challenging shout

So i found a bug, atleast i think it’s a bug.
When using challenging shout, it falls off in 9 or so seconds. I buffed the duration with items, so the tooltip says 13,62 seconds. I´m using “increased crowd control duration” affixes and "exploiter, smiting " imprint to increase duration. I stay “healthy” during the effect, so it doesn’t fall off due to the smiting imprint.

i experience the same

Yep, noticed the same problem. Got it up to 14 seconds yet still lasts under 8…
