this will cast chain lightning the first time you hit it then lighting bolt the second then healing wave the third. then it will cast chain lightning, then lightning bolt, etc it's like having 1 button do something diffrent each time you push it.

You should read the sticky macro codex at the top of this section it will help you understand macros ALOT better.

You can limp through alot without macros that are too extravagent but the goal is to play 5 toons as close to as well as 5 people would with extream coordination. what good is 5 nukes on the same target if it takes you 6 seconds to get the cast off. You would be dead before anything can happen in PvP.

I try to tweek my macros to compensate for things that are 5x dangerous in PvP like the delay when you pick a target send thst to the server then you an attack on your clones. Well slow heals are useless so you should have a key to heal each of your toons by name so that you don't have to target them and wait when time is what you don't have. why spend the time to cast healing wave when you can cast 4 lesser healing waves in half the time for more healing?

Read the sticky up top and if you have any more questions reply and we can hook you up. Welcome to the forums, have fun and good luck.
for fun I created my own personal 'pewpew' macro using rank 1 lighnting bolt. What it does is have an alternate cast sequence with gaps so that each shaman casts one in succession. So I can spam the macro button and get a constant stream of little lightning bolts, its not really useful just looks freaking sweet lol. My 3rd hdd and extra ram arrived today so ill see if I can fraps it

The macro codex sticky and the http://www.wowwiki.com/HOWTO:_Make_a_Macro page are excellent sources for learning the basics on making macros and cast sequences.

Oh one other thing I found is that you will want to build in a reset to them even if you dont think you will need it. Due to lag it will sometimes skip sequences on me and the next time I hit the key I will get duplicate casts thus wasting mana. Currently all my totem macros have a reset=60 so after 60 seconds it will reset, might make it less like 30-45 depending on how things go.
