Hello all

There is something off with the Briarheart set on combat metrics and others atm. I dunno what it is, but maybe someone knows something?
The setup: StamSorc with Briarheart frontbar only. Two daggers, 3 body.
(VO,, stormfist, yadayada others - consistant in testing) anyway:
The set says uptime of 10 sec, cooldown 15 sec. So 5 sec with nothing, fair enough.
YET: The lowest uptime my Addons say is 90%, the highest on testing was 98%. 30+ test-dummy-runs is in between both of those numbers.
How is this possible? Does it mix the healing into it? How can I see what the actual uptime of Briarheart is? (the weapon dmg proc to be exact)
Thanks!,
Nun
