Personally, I wish they would put item-level requirements in leveling dungeons. >w>()
You wouldn't believe the number of times I've gotten ARR or HW dungeons where people would wear whatever they could just to be able to queue for the dungeon.
I've had dungeons run where both DPS were wearing crafting and/or gathering gear or runs where the tank wore caster/healer gear.
They should make NQ leveling gear cheaper and more readily available too.
