Hey KenLeeZA good to hear that you are progressing well!
I agree some of the fights can be troublesome with movement. Which fights are you having trouble with in particular? What difficulty are you working on? What ilvl is your gear?
I use follow mainly but also setup a strafe left and right key. This will get you out of most bad mechanics much quicker than following.
There are sample formations in the ISBoxer toolkit under Base hotkeys. I use the Line formation to spread my characters. All you need to do is setup a hotkey that you want to use to perform the spread and make Make sure your movement keys are configured correctly under Variable Keystrokes.
It is fairly self explanatory from that point but if you need additional assistance i could probably post a couple screenshots to help you on your way.
