Ive been using /castrandom and now im about to try the cast sequence when i set my toons up for an instance .. one question thought.. what are all the commas added in here for? Ive checked wikis and such on castsequence macros but i cant find where it says to EVER use more than 1 comma?

EXAMPLE

Druid /castsequence [target=party1Target] reset=combat Wrath, Wrath, Wrath,,,,,,,,, <--- Theres around 9 ... ?
Druid /castsequence [target=TankName] reset=combat ,,,,Lifebloom, Rejuvenation, Lifebloom, Lifebloom, <--- Theres 4 in there between combat and Lifebloom

I dont want to sound like a noob , but unfortunately thats what i am on this subject. ?(
