Hey guys I have been dual-boxing off and on for awhile, but I started a Shaman Duo last night.

I have searched the forums, but I seem to always find stuff about 3,4,5 or 5 boxing shamans but never 2.

So here are my macro Questions.

1. Whats a Good healing Macro for my duo.
I'd like one where with a normal Click my alt heals my main.
Shift-Click(or some modifier) Heals my alt with my main.
Alt+Click Heals Main with Both alt and main
THen is there another Modifier where both Heal my alt?

2. What is a mana effective cast-sequence for leveling up 2 Shamans. I right now pretty much spam Lightning Bolt. They are only level 20 so please no upper level spells..

3. What Totems if any should I use while leveling? I really don't use many right now. Occasionally on a tougher foe, but that is it.

Well I hope someone can answer this for me.
Thanks in Advance
