A lot of people who don't usually roll as a MNK don't realize that you can ride that line between flank and rear - sidestepping a foot to the left and right to land all your hits correctly.

Many I've spoke to (for some reason) believe that you have to be dead center on the rear or flank or it won't be position'y enough.

So much so that I've actually been yelled at before because someone thought I wasn't even moving to land my positionals. I was just riding the line. It's right there on the screen so long as you have the targeting circles turned on, on your HUD.

Regardless, and now that I really think about the correlation, maybe some think the positionals are hard because they don't know about the line - in conjunction with the "pain" of having to memorize which position to be in at which time.

To which, none of it is hard. Easier than having to pay attention to a proc as far as I'm concerned.
