It would seem that, thanks to Manajuma's blade having MF, the witch doctor should actually be the preferred class for magic finding. This is because according to this site's guide, no other weapons can roll MF.

However, WD is kind of underpowered compared to other classes at the present time, as far as I can tell. The extra time it takes to clear packs cancels out any benefit that you may get with your extra MF.

For the time being, I would really like to know if anyone has been successful in doing Act 1 speed runs with a doctor. What skill build are you running, and how much MF do you have? Or conversely, has anyone really tried to make this work and it is just not viable because other classes are so much faster?

As far as I know, Sun Keeper and The Three Hundredth Spear are 1handers that can roll up to 25% MF, good for the templar since dps doesn't matter. There is also a 2hand sword with MF also but I forget the name.

With the 1.04 changes, it isn't to hard to get 300 MF without needing to add MF to your weapon
