On the flipside, imagine running SM EV for the first time in Dread Guard? Any halfway decent player would find no challenge while vastly overgearing it. Anyone finding it difficult in that gear would likely be so clueless at their class it would be painful.
Not even full DG gear will keep them alive at Soa if they stay in the middle when the floor falls down, or go the wrong way on the platforms, or lag behind the group and miss the heals. And if the clueless player is a healer, they'll likely doom the entire group by healing improperly or not at all during the descent.
