So hoarding packs before major nerfs will be a good dust strat, if you have a good collection.
There's a caveat here: once you receive a card, you'll have it marked for "collected" purposes. So if you disenchant a card you've received, it's still considered "owned." So you can't exploit the refund system that way.
There's a great benefit to this though: If you don't like a particular card or class, you can disenchant them and not have to worry about getting them in future packs.
And how long is the card will be marked "collected"? For example, I've opened an epic I don't want so I dust it right away. But if I already collected other epics I would like yto have them all again.
Forever. Once you've collected a card, you've collected it.
