Rolling HoT's on party

Did you intend to have two lines for the tank? If so, I'd just suggest doing

/castsequence [@TANK] regrowth,,,,, ,,,,, rejuvenation,,,,, ,,,,, ,,,,, ,,,,,

That might be it but can't be sure. Basically, if your macro ever resets it will wait until you cast regrowth before it falls through again. If that happens, have you tried just pressing the spam key once every GCD and see if that unsticks things?

My goal was to have both regrowth (27 sec) + rejuv (18 sec) on tank at all times and since they have different durations i needed to separate them.

Oh yeah, and pressing key only once / gcd is something i will never learn! :P
