Hmm I guess it works properly then. I just didn't really notice a consistent damage increase on blue ~35 two handers.( eg: normal hits around 160-180, never go over 200 with wf procs while they should, non crit).
I would like to see a level 40 or 50 (or even 60) with 3/3 in elemental weapons and a nice slow speed two hander, that can test with enough data to see if there is consistency in the wf procs.
