I don't necessarily disagree with the request, but the leveling dungeons are part of the MSQ, and so for new players to be suddenly told, "You need to go farm old dungeons and / or purchase vendor or play gear to meet the ilevel requirements of the new leveling dungeons," is off-putting, to say the least. In fact, this is likely why there are no ilevel requirements as it is, for S-E does not want players to quit the game because they have to do that, when they just want a story experience. What I think is a much more prudent change, is an ilevel upscale, assuming you meet the dungeon's physical level requirement.
