W101 made it this way. It prevents low level players from getting tons of gold, XP, and gear. On its May 2011 update, it says, "Are you Legendary enough?" It was pretty much made for the Legendary wizards, not anything below it.
What good would it also be for a low level to tag along with you? That low level could be replaced with a Legendary. The dungeon is too hard for anything below Grandmaster, and yet, not even a Grandmaster can go in! It takes a while, too! You also need to keep track of whether it is blade or traps in the final boss, and you also need to know the right time to attack. Attack too early, probably not too much damage, but attack too late, and you are in serious trouble.

It also dissuades another level 60 from jumping in on the very last boss for the kill shot. In other words, not helping in the dungeon and only getting the loot.
