Howdy Yaga and welcome to the forums!

in general, this won't work. yes it will for very short distances.. like strafe left and right, take a few steps forward and back... but it will quickly fall apart.

this is due to every character having a different heading (forgetting starting position)... if you just hit W to move them all forward, in a very short time, you will see their paths start to diverge. this is due to their heading being precise to the hundredth of a degree (a guess).

this is also forgetting that in a fight, there is a very high chance your character will turn to follow or get feared. the end result, you need to be able to recover, re-orient, and re-acquire your targets quickly.. and /follow is about it

i hope that explains it.
