- Downside to this is mana used, but at least they are doing some damage while they are turning to face the mob lol.

Note: I have not testing if you can cast a Channeling spell on a mob thats at your back, but maybe there is a command to make your character do a 180 turn.
You can't.
Oh and it wont wont work to cast the next spell too soon, as I don't believe there's any of the auto-facing abilities that wont trigger your global cooldown.

What I usually do is that I turn off autofollow on any alts about 20 yards from my target. Should I need to turn them around again (in which case the mob will have moved at least 21 yards and I'll most likely be right behind it on the main) I just turn on auto-follow for an instant and then switch it back off (wont be interrupting anything if I can't cast).
