Useful Healing Macros

[Bixby]

is there a way to chain it if the cooldown is longer than 60s?

I think multiple /waits work. Haven't actually tested it, though.
/wait 60
/wait 30
for a 90 second CD.

now, on its own..the above macro works. but if u cast another spell after that..then it wont work for some reason..any ideas?

You can cast other spells if they're pulled straight out of the abilities menu. You can't use other macros. You can only have one macro running at a time. Using a macro while another is still running kills the first one and starts the second. The only thing you can really do about it is not rely on long /waits, avoid using macros for other spells, and/or stick use /recasts in macros that you use more often (e.g., put /recast Swiftcast in your Cure II macro so you get that information in your chat log regularly).
