Testing the sim with the newly implemented TAiaJ, I've noticed that the bonus swings generated by it do not appear to generate other procs such as FC at the moment.
I've also noticed that the simulator seems to get much higher numbers out of BCB. At least part of this appears to be that BCB is currently programmed to benefit from Tundra stalker, but using a single
[Mace] I can confirm that BCB only benefits from multipliers that affect white swings.
Tests were done with no trinkets and no str-affecting procs - data over 1009 white swings
white swings damage - 496-503
Diseaseless BCB hits - 124-126
Frost Fever BCB hits - 186-189
Blood Plague BCB hits - 186-189
both diseases BCB hits - 248-252
The simulator also doesn't appear to be treating offhand procs of BCB correctly, not treating the swings as offhand hits (-50%). This Sim parse is from my current gear/spec (2/3 BCB) with the points from Nerves of cold steel removed, so offhand swings from BCB should be ~50% of the mainhand ones:
