Ever been to see El Tiburon, and he just ripped you apart? Yes? That flanking can really tear you up, but wait! I have a picture that might make you go . . . Ohhhhhhhh, I GET IT!
Yup, all you gotta do is back your party into a corner or an edge, and you've just cut flanking out of the equation. It's as easy as that . . . apparently it's almost as easy as making grandmas rock out with Photobooth.
