During the Open Beta the Witch Doctor was one of my favorite classes to play. More than the other classes, I felt like the level 13 witch doctor had the most customizability of play styles. Eventually I had a witch doctor using the zombie hands skill with the rune and the firebat skill with the rune as my left/right mouse buttons.
I quickly discovered that when you are out of mana with a witch doctor, you cannot perform a normal attack if you don't have normal attack bound to a key. When playing the wizard and demon hunter, however, they will both perform their normal attacks if they do not have the mana for the currently bound right/left-mouse key attack.
I regret not testing to see if this was because my wizard and demon hunter had long range weapons equipped, or if it was because of different attack/mana-use mechanics of the three classes.
Has anyone else encountered and tested this problem? This was the only mechanic of the witch doctor which got me down...
