That's how it should, yes. But I just want to make sure that HoJ is still the beauty that it is here as well.
Here is forum talk from 1.9 about it.And here is a screenshot of me with HoJAnd no, that is not a picture of HoJ proc'ing WF. For all we know it could've been the auto attack instead. Both the stormstrike, auto, WF proc, HoJ all happen at the same time on my screen and in the combat log, due to them all proc'in at the same time. So it can be hard to discern from which is the Auto Attack swing, and which is the HoJ proc. Because they're both the same, and HoJ doesn't tell you when it procs in the combat log. But you will see the blue flash under your character when it does.
But the point is that the extra attack off HoJ can also proc WF, due to it being a "weapon hit" - What this means is that theoretically it is possible to get a WF procs like this if you're
EXTREMELY lucky:
Stormstrike 1 (+2 WF hits)
Auto Attack 1 (+2 WF hits)
HoJ attack 1 (+2 WF hits)
You could get 9 hits in an instant, if the planets aligned for you. Personally I've only had that happen once or twice for me. But the usual result of these all proc'ing are about 5-7 hits. The 9 hit wonder is very rare.
