I've said this before, but:
All common and rare armor and weapons should be able to go Legendary just like the Husk Of The Pit. In fact they could make it have stages with a bounty to get from one class to the next (i.e. Common to uncommon). As a side affect, this would make the non legendary weapons & armor sold in the tower a more viable option.
I actually kept a common helmet on my Hunter until I got a legendary drop, dismantling everything else because I like the scarf or ski mask on it. And to remind me of what I lost I saw a group of Titans in the tower, different race and genders all wearing the exact same raid gear and 3 of them had the same shader from Eris.
Clones...
