I'm having trouble with [nochanneling], heres my macro:

/castsequence [target=gaggle] [nochanneling] reset=15 Power Word: Shield, Penance, Greater Heal, Greater Heal, Flash Heal, Penance, Greater Heal

it keeps clipping off the 3rd heal of my penance. If i put nochanneling before the target, it doesn't seem to clip, but it also won't target gaggle and only selfcasts everything.

any ideas what i'm doing wrong?

thx.
