Alright, so I've been at 90 for a while now and been doing alright numbers, being an affliction lock. Although, I am a bit confused about when to refresh the dots. Like, I apply them- and when there's just under 50% left, I refresh them. And as far as I know - that's when you get them to last much longer. However - when do you apply them again then? just under 50% or as they're about to expire?
