Imagine if after that weekend Xur sold Prometheus Lens that it disappeared from all loot pools and would never be in Xur’s inventory again. Now imagine they never nerfed it, that’s Felwinter’s Lie in a nutshell. Any gear that outclasses everything else by such a huge margin simply proves how weak and boring a majority of the loot pool is by comparison. Name one shotgun as good as Felwinter, or one grenade launcher as good as mountaintop, or one sword as good as guillotine.
