Witch Doctor Waka

Not sure if this is known or not but there is an issue at the beginning of the game with the KFM and the Hajoon quests. At the Depleted Mine Hajoon wants you to do a combo to pass his training. However the combo requires a skill that isn't available until Level 18 (Pretty sure it's leading palm). Even if you do all the blue quests leading up to this point there is no way you'd be level 18 by this point. I ended up having to run back after basically beating most of the first act just to finish those quests for Hajoon.
