[quote]Why change this ?[/quote] They wanted to shift players into ranking up Rahool instead, so they made him the only source for new exotics and replaced the armor in lost sectors with engrams. Recently they got rid of his ranking system but kept the lost sector thing the same. [quote]And wasn't there a way of getting exotics of rahool that you'd not unlocked for a few materials?[/quote] It's still there under Focused Decoding, it's named 'Novel Decryption' - costs a Cipher + Exotic Engram. It does not include exotics from TFS or Year of Prophecy until you unlock them from one of their expansion sources (ie Sieve or Legendary campaign) first.
