For dash I suggest no animation at all. It is so annoying to have to press a button every time you want to dash. Solve the issue like Pathfinder Kingmaker did in their turn based mode. Have a line between your character and where your mouse is pointing (like we have now) and change the color of the line to red (or some other color) to indicate that going past a certain point would use your dash action. This would speed up turns and make the game flow better.
