I like using Alt+Mouse 2 (in some cases it is Ctrl+Mouse 2) a lot when managing units and small armies. Would be really nice if this was added to improve overall path finding.
Of course, if it was optional, that would be even better! A toggleable checkbox for it in the game settings would be awesome.
Opinions on this feature would be nice. Since it would be optional, it shouldn’t cause any issues to people used to the old way of path finding.
In my case, I didn’t know what Alt(or Ctrl)+Secondary click was until some months ago, when watching a video review on the game. I also think many people does not know about this way to change the AI behavior, newcomers + casual players, mostly.
