Given how the console controller was mentioned, those are not the kind of movements I was picturing. Those are kind of WoW-esque.
I think your point would be better expressed with “movement bindable to keys”, which would mean the movement you described could be bindable, it would not be binded by default, and the user would take care of remapping the skill keys to compliment the movement scheme they prefer.
With the option available but not supported as an official scheme, then the need for a separated interface would vanish.
First let’s get rid of the “click to move” comparison. Click to move is totally different from mouse movement, where there is no clicking but you keep your finger on the mouse button and guide your character with the mouse.
There are many games out there with both systems, it’s just a matter of allowing keybinds to be changed. Personally, I’m so used to mouse moving that I find WASD impossible, and have declined to play many games which don’t offer the possibility of mouse moving and was relieved to find this game is perfect in that respect.
