It was already in the first game quite an issue, that two wands were better than one staff. The offer range attack instead of melee and in combination better stat boost than one lonely staff tends to over. Though in D:OS2 wand + shields often is even better, because of Shield throw and armor replenishment.
Many of the issues regarding items carried over from the first game or even got worse sadly.
Only purpose now for a staff could be full magic setup with a warrior who uses a staff for close combat magical damage.
