1 Resto Shaman + 3 Elemental Shaman + 1 Pally tank Macros

[Decadence]

So I haven't played this combo since I posted this since I've been leveling the mage + shaman's in PVP.

Another question (this has probably been covered somewhere but I haven't seen it).

How should i do my healer macro

the 3 options I can think of are this:

1. /cast target=focustargettarget Healing Spell

2. /cast target=focus Healing Spell

3. assign a name in the macro and /cast target=name Healing Spell

4. /cast [harm] Lightning Bolt; [help] Healing Spell (this would make my other chars useless when targeting someone to heal)

I'm leaning towards #1, but after I get what method to use out of the way what should my healing macro look like? I've only done Elemental since wotlk, I know in BC it was spam chain heal in raids and lesser healing wave in heroics.

/cast sequence [target=focustargettarget] reset=combat Earth Shield,Lesser Healing Wave,Lesser Healing Wave,Chain Heal,Lesser Healing Wave,Lesser Healing Wave,Chain Heal,Lesser Healing Wave,Lesser Healing Wave,Chain Heal,Lesser Healing Wave,Chain Heal

That's 252 characters, but I'm not sure if its the right spells. any advise would be nice with this.
