I love these videos! For me, I personally tend to open enough at launch that I have all the common and rares, most of the epics, and then around 15 legendaries from the set. I then hold dust, wait to see what I want to craft, and go from there.
I also track how many packs I've opened from each set without a legendary opening. That way if I am close to getting a legendary card from the "pity timer" I can decide if I want to buy packs in that set. Which I tend to do buying one at a time since I am really just going after the legendary and don't want to waste gold on extra "dust packs".
EDIT: I also tend to start hoarding gold about halfway through the expansion.
