"Move only" keybinding that does not exist, but it should.

With so many move + attack and or attack only hold position etc. keybindings. I assume there is a reason the developers intentionally did not implement a "move only keybinding". It is very common button in other games so that when pressed, you will never attack, you will only walk in the direction of the cursor and/or click. Currently when chasing a target, you have to move the mouse off your target just to continue walking forward then whip the mouse back to the target for each new attack move command. Imagine a world with a move only keybinding, you would just hover the mouse over intended target the entire time, 1 click to move/chase, and a different click to issue attack. No more whipping the mouse back and forth on/off the target just to run in that direction, making misclicks a thing of the past. Even professionals misclick/wrong target. A simple move only key would be a great quality of life improvement for me, others, professionals, and decrease the amount of tendonitis associated with very rapid mouse flick movements back and forth (>4 mouse movements per second assuming high level autoattack animation cancelling at ~2 attacks/second.) Less tendonitis = more playtime for all, higher fanbase, more money? Or am I wrong? Please comment, agree, disagree, correct me if I am wrong and pass this on to developer/moderators or whoever could answer: why there is no "move only" keybinding.
