Help with a healing macro

[Nolife]

You can do it with a macro like this:

/castsequence [@player] reset=2 Renew, NULL
/castsequence [@party1] reset=2 Renew,Renew, NULL
/castsequence [@party2] reset=2 Renew,Renew,Renew, NULL
/castsequence [@party3] reset=2 Renew,Renew,Renew,Renew, NULL
/castsequence [@party4] reset=2 Renew,Renew,Renew,Renew,Renew, NULL

Spam it, wait for couple of seconds to reset, repeat, profit?
You need a macro extender for this macro.

Reason why Renew is repeated so many times is that all castsequences which have the same spell as next step will advance forward when triggered. (Make sense?)

I would strongly recommend adapting to healing style where you only heal when necessary. Your mana won't last if you spam heal at 85.
