I just use my arrow keys to go forward/back and strafe left and right on my toons, simple and effective.

Just leave your guys stacked together on 1, i know if you spread them out in a light or whatever formation it looks cool but when it comes time to move out of something its just annoying as you have 4 seperate guys to check arent standing in something they shouldnt be.

You stack them together (which they will be if they follow you anyway) and you essentially have to move 1 toon out of something, not 4.
