Not in a game..... You just make PvP engrams drop absolutely NO weapons or armour...(materials/motes/the odd strange coin etc)..No seperate perks for PvE/PvP.......no need to complain.....and for those that are infatuated with PvP and having the best weaponry......they have to step into PvE to try RNG the goods ...... Remember Destiny was created and only exists because of that once amazing premise of an open world mmofps
