for positionals keep in mind that you dont have to walk the entire 90 degree from the middle of the back to the middle of th side and then back again.

when you target enemies the circle you see on the ground around them helps you. there where its open is the back area. you can just stand where the circle starts and only do a few steps to reach the necessary position.

if enemies dont have that open area in the circle you dont have to care about positionals at all.
