It isn't just IB, it's Challenge of Elders, King's Fall, Court of Oryx, pretty much any PvE content too. It's absolutely INSANE I run 3x 335's and get 334 drops. And exotic engrams that are supposed to decrypt "at or above your current light" decrypting at 334 when my light is 335? It's so bad I keep a 334 weapon on each character just so I can DROP my light before opening a raid chest, match rewards being given, or decrypting an engram at Rahool/Ives. I lost count of how many ~300 light blue class items I got as rank up rewards from this IB. I'm not a PvP guy in Destiny, the pitiful rewards I got from actually getting myself up to IB Rank 5 for the first time ever don't make me really very interested in ever doing IB again. And through my entire time playing IB not a single Nirwen's dropped for me though I got half a dozen crap sniper rifles. At least the Nirwen's that Saladin is selling was a really good one, so I bought it.
