[2023] Why can't I use left click to attack and move? No stand-in-place?

No, it works. Assign a skill slot to your left click. If your mouse is over an enemy it will use the skill, otherwise you will walk. Hold shift to stand still and force the ability to be used.

I think something is not being communicated properly because I also just tested it again right now and as far as I can tell it works with Swipe, Tempest Strike, Flurry (melee), Flurry (bow), Puncture (melee), Puncture (bow), Fireball, Lightning Blast, Flame Reave and Mana Strike. If you are experiencing something different, please open a bug report with details on the specific interaction.

I didn’t check a throwing ability but it really shouldn’t be any different. Also checked Javelin, Hammer Throw and Acid Flask. All good.
