It's been auto-pass for months and months now in CT/ST (May have changed when they stopped being weekly lockout? Everyone greeds on everything now, so haven't noticed). Dungeons don't auto-pass if you don't roll. Chances are likely that this is just a copypaste from the CT loot rules
Yeah, it's the entire point of this thread. The prelim notes just don't seem to note the change with loot they did with LotA/ST (specifically, if there is a weekly loot limit, you don't get drops unless you lot, which is how it should be) and people just want to make sure they don't regress back to the old ways with WoD.

But you know, since it's the official forums, people have to argue against good changes simply for the sake of arguing.
