I am in the process of updating the simc warlock module for 5.4. Does anybody have some data to explain how the RoF on the current PTR generates Embers?
It looks like a small chance on every tick to create 2 ember bits.... This might be the crit chance, but it is not tied to critical ticks.
Additionally, if it only hits one target, it typically creates only 2 ember bits. If it hits two targets it typically generates 6-8, so it might be handling the first target differently (and how to define which target is the first one).
As you can see this isn't really clear, so I could use some help from you guys. Step on the PTR, hit the raiding dummy/ies and take note of number of roF ticks/crits and ember bits. If somebody has a twitter account that GC replies to, maybe somebody can ask him how it is supposed to work.
It still has a chance to generate emberbits, but at a much lower chance than the live iteration. It averages out to something like 0.4 emberbits per rain of fire tick on live and like 0.25 on PTR.
