i was on ptr last night with 3 shamans - and i found out a way that, even though crude, works for making a line!

on my topright shaman, i binded the 'optional' right strafe to caps lock, on my left shaman, i binded the 'optional' left strafe to caps lock, and on my main, i binded the 'optional' backwards key to caps lock. Now we know that when you press a movement key on your main it kind of 'lags' somewhat before you characters move, so i just held the capslock button till my main reached the other 2 shamans, and by the time the rest caught up they spread out in a line lovely. i don't have a screenie since my norton decided to fk my computer up, but, althought it's somewhat crude, it works!
