How to heal lolz ?

i have been boxing for some time now and want to get to the next level: HC farming, i got a prot paladin as main and im thinking on makeing 4shaman's or 3shamans 1boomkin druid.. but then i forgot i never have been in need for heals then i just was boxing 2mages becurse the mobs never did hit me . so now i want to know how i make a macro that heals party members.
im not sure how to make it i was thinking it was something like /target player name /cast Chain heal with a macro to each of the party members but with all those macros it will fill out all of my bars so what do i do ?:D

There as many ways to do it as you have keys on the keyboard. Who are your healers? Who are you healing?
Basic Macro is "/cast (targetname) heal spell" Then you can use modifiers to change the healed or healer or both. Another simple way is use a heal add-on like HealBot and use mouse broadcasting, or /click through mouse.

Hmm okay thanks

This comes up quite alot, so I'll post my usual response.

When you have multiple shammies, in the simplest case you need just two keys:

- Somebody heal the tank (only one guy responds):
/stopcasting
/cast [target=tankName] Lesser Healing Wave

- OMG AoE damage (all guys respond):
/stopcasting
/cast [target=player] Chain Heal (or just LHW if you prefer)

There really are HUNDREDS of ways to heal, but this is the very simplest and if you have a decent geared tank will see you through heroics.
