I'm using the downtime while my computer is at the repair shop to build some macros. Can anyone check if my syntax is correct or if I'm missing something.

/target Deev [noharm, exists, nodead]
/castsequence reset=combat [nocombat] Water Shield(), Earth Shield()
/cast Riptide()

Meant to:
a- Target my tank if he is there, and not dead, and not charmed or similar.
b- if not in combat it should cast water shield then earthshield.
c- if the castsequence fails due to [nocombat] it should skip to the third line and cast riptide on it's target.




Off-topic:
Repeater Regions, does it work as stand alone or only with Isboxer? I'm new to running both tank and healer, so I'm trying to figure it all out.

Thanks in advance
