I suppose I didn't include my macros I'm currently using...

I haven't done much with focus as of yet... my current macros are as follows:
Invite macro (for inviting all chars to party)
Target pally
Assist Pally
Follow Pally
Lightning Bolt: #showtooltip Lightning Bolt /assist pally /cast lightning bolt
Healing Wave: /target pally /cast Healing Wave
Heal Self: /cast [target=player] Healing Wave

the current pitfalls that I see myself getting into are - trouble with pulling things as they all just kinda follow the tank rather closely, randomly not correctly facing the target (which has happened a few times), taking random target specific damage (thinking of making a heal macro for each of the players individually that I could hit... binding to shift+number), and just positioning issues in general - standing in stuff or being too close to the tank while doing ranged attacks.

Also - is it even worth it to bind Earth Shock? I mean of course I could use it to interrupt casts... but blowing it on all 4 shamans seems like a waste. Not really sure there is much to interrupt until northrend either to be honest... Also not totally sure what I'm going to do with totems... but that will come with time I'm sure.

In any case... 5 box questing really sucks imo... can't wait to start doing instances.
