AFAIK the proc is 1 RPPM. It can for sure override itself which is why I often do my best to spend it quickly instead of sitting on it.
Those are just single trinket sims, so they're not that valuable. If the trinket combination sims reflect that as well then I'll look into the APL — my guess in that situation would be that Simcraft is either overvaluing haste (typical) or the 2-pc bonus is inflating the value of a haste proc. Either way I think in practice BMC is much stronger, especially when you take into account multiple targets, or ember saturation from shadowburn.Why do you think bmc is valued so low on the trinket chart? It seems like having the over budgeted int along with a stacking buff where you could time cbs/sbs with really high multistrike, it would be great for destro. Or is it that darmac's haste buff just allows you to gen enders that much quicker giving you more spenders overall?
