(Mouse Mode)
[Left mouse button] set to movement only without auto-attacking or interacting?
In Challenge Mode for example, the number of mobs is absurd and I have many times died because my [left mouse button] did not move my character, but makes her auto-attack instead.
Whenever I do Challenge Mode or Bosses, I have to put off my companion as it blocks my left clicking.
P/s: Make [left mouse button] moves your character in the general direction of your mouse and not the exact point that you clicked.
In some maps with irregularities, I often clicked at unclickable area (the black part on the minimap). My character then just stood still waiting to be killed.
