Legendary Weapons, why?

[Ancient Mariner]

I have a different take on why they might have legendary weapons and why they could be put to good use in the future.

They could be giving out these high level weapons to get us ready for the long awaited next chapter, I would hope that it would come with many higher level enemies and tougher bosses. Otherwise no there is no real good reason to have such high level weapons in the current game in my opinion.
