I've been saying this since early Y1.... PvP and PvE elements being tied together ruin the balance for PvE (seeing as to how they only seem to improve 'balance' in PvE). A prime example was the hellish nerfing of the Mythoclast. It needed to be balanced for PvP, yes, but it was a rare gun and should have had that nice shiny edge of supremacy in PvE. I don't like nerfing old guns tbh.... They can all have relevance, with different and actual 'new' perks that make the guns not more powerful, but interesting and have an advantage unique to that gun.
