Still on the movement subject...I use WASD to move my tank, on the do-not-pass list. For everyone else, I rebound the movement keys to

Insert Home PgUp
Del End PgDwn

So it looks like the
QWE
ASD
setup.

That way, when the occasion arises that I need to move them out of the fire, etc., I can use that set of keys for the clones, and WASD for the tank. I just tap one of those keys when I want to take them off follow. I've never found that I wanted a spread-out command in PvE, and I like them within chain heal distance of each other.
