I fail to see how this one time event, is going to "invalidate quest rewards." What? That green quest reward isn't going to be an upgrade? Oh big deal. By 110 that's when the quest rewards matter anyhow. The more gear I get to break, and pass off to the enchanter in my guild for materials, the better.
It's this, or sit in battlegrounds, or trashran. I much prefer this for gearing alts.
