So with any luck, I SHOULD get my fourth tier pice this week (I'm an optimist, what can I say). One thing I've been wondering about it though:
If it procs while you're still on Low Stagger, should you use it immediately to clear what you have so you don't waste another potential proc? Or should you hold onto it until you would want to Purify normally, even if that could be for quite a few seconds?
