Here's how it's going to happen: Those "Under-rated Exotics will be able for acquisition for Year 2. Then we will get the new Year 2 Exotics Then those "Under-rated" Year 1 Exotics will go right back into the Vault as we play with our new and (probably) better toys. There is generally a reason those Exotics are neglected in the first place. Whether they just weren't worth the Exotic slot, or Bungie nerfed them into the ground.
