That is not possible. Any level of variation will cause the characters to veer off more and more drastically. Follow works perfectly well, there is no reason to avoid using it. Even at points where you want to move slaves without follow, there are more effective options, such as passing movement keys or strafing. Again, hecause of variance, these are short-distance use only.

Using the mouse and click to move is only advisable in limited situations, such as a point where a toon needs to be anywhere other than where they currently are. But in that situation, its still faster and more accurate to actually swap to that screen and move than to trigger mouse broadcasting and hoping it clicks somewhere that A - isn't worse thatn where you currently are B - doesn't cause your slave to just run forever C - doesn't run them into other mobs D - can even be reached because if it cant then the slave may not go anywhere at all.
