Don’t most, if not all, exotic weapons have either Soulbound on Use or Soulbound on Acquire attached to them though? I havn’t checked out Exotic or Legendary weapons yet because I’m not level 80 and don’t think they’d be worth the investment as is, considering I would out level it in a matter of a few hours (on a good night).
*Edited to add the fact that I wanted to say I do like the idea, though.
