I am starting a new team of druids and was going to dedicate one to resto. I am wondering how would I go about building a macro that could round-robin cast rejuv on the team without using a RR key?

Maybe having a group of macros that are fired off by /click

Code:
button a 
/click buttonb 
/click buttonc 
/click buttond 
/click buttone 


buttonb 
/cast [target=druida] rejuventation 
etc
Or would I have to make it a /castsequence [target=druida] rejuvenation,,,,

because of the GC?



TIA
