3 of Coins, iron lord bounties, archon's forge, and nightfall are PvE. That's 4 PvE activities for max light. And it may bug you, but it makes sense to patch PvP more than PvE because PvE isn't nearly as precise and the game can't be really ruined because of one OP skill or gun. Part of what makes Destiny what it is, is the way they combine PvP with PvE. It's annoying for mainly PvE players when stuff gets nerfed, no doubt about it. But would you rather money is spent on making fresh PvE content, or doing specific PvE balancing and separating all the weapons? I know what I'd pick any day.
