Video in description. Proc rate is great with frenzy and stacked AS.
nice for trying but i've tried that build and I've watched your video and the proc rate is still extremely low, still much too low to be viable and even on T6 like in the vid its slower than T6 clear builds. You may be confusing your mirinae proc for the Rime...Rime only procs on frozen targets which is for like 1-2 short time period after Leap...thus only allowing 2-3 frenzy on only 1 target trying to proc.
Rimeheart only works best when the mobs don't have max Diminishing Returns on Frozen and can stay frozen long enough to be hit enough time to possibly proc it. So the best way at least for barb is One frozen charge over a pack (not twice over same mobs because it adds another DR stack) and immediately Cold Seismic Slam spam with Frostburn gloves
Cold Leapquake has such a low proc coefficient it hardly ever procs, ever.
Reakor's procs more a lot more when you get a good pack going but 2 handers are doing way more dmg
