I’m actually surprised it isn’t available by default, as alternative control schemes like this in isometric RPG’s is as old as Neverwinter Nights 1 back in the early 2000’s.

Larian seems to have great attention to detail, so I wonder if they’ll add it in a patch.

If it’s anything like the gamepad controls (which also let you walk around like an MMO but don’t require a mod) they will still happily walk through every inch of danger and pain they see, taking needless amounts of damage in the process.
