Looking for hang-ups 6.2 shadow

Just wanted to share this and see if anyone notices any potential problems.
Orginally I got it off this board but can’t remember where or when. And just been tweeking
the little things.

Sequences['Shadowtest'] = {
StepFunction = [[
	limit = limit or 1
	if step == limit then
		limit = limit % #macros + 1
		step = 1
		step = step % #macros + 1
PreMacro = [[

talents please!!!???

I have been using your macro today for leveling my 96 priest…works great so far, no hang ups for me. I just added “power word: shield” after the “mind blast” lines…just to be extra lazy.

Looks like the only talent you really need is Cascade for this…
