Latherus, has a well written post on the Bug Section thread involving his personal experience with the issue from a Witch Doctor's perspective, even pre-patch. Long read, but informative none the less.
Have you tried a one handed sword vs a one handed axe with same APS?
I made that switch recently and felt like my kiting ability went to pot, but I have no evidence, just thought you might have tried that combo.
Yes, I have tried that combo, but only in regards to frenzy, bash, cleave, and basic attack. I have not tested it with any other skill combinations, ect.
Imo, one hand spears and daggers seem to have the most potential to be non-normalized to have much less of a movement lockout time then expected, and thats only taking into account my experience and not including dual wield. Maces, swords, and axes for me were much harder to visually comfirm irregularities, but "feel" like there also is some disparity between the movement lockout times of the types.
Again, more case by case research is needed...
Edit: For anyone willing to spare some time to test, very cheap normal weapon types sell for under 1000 gold a piece on the AH, if not under 200 gold. For those of you willing to look into it, the investment has a very small cost but mainly the time you put into it in relation to your specific case.
