Some weapons just aren't built for PvP. Combined with play style and tactical ingenuity, many weapons can be utilized in both environments. But there are many weapons that between their handling, reloading, damage effect type and area, will straight up work in only one of the environments. I've got a full auto Stolen Will that will destroy PvE enemies but is about 25% reliable in the Crucible. After shooting my Spare Change for a bit, the handling and RoF on the weapon just doesn't allow for the quick and precise nature of the Crucible. It's strong and hits solid, but is too bulky and cumbersome to move with the fluidity required in Crucible combat. Lastly, it's just my opinion and if it works for you, well, tear it up and have some fun!! 😁 I really enjoy this game and I feel it's meant to be played with what you get. The rolls and gear that just so happen to add up to your experience and yours alone. You will find weapons you like, and weapons you don't. But you must try and test to find those that really speak to you and play the best in your style. These "God Roll" weapons everyone chases after are only good in certain situations and actually will limit the myriad of ways you can experience Destiny. Bungie wants us to create our own legend and will continue to modify and expound the game accordingly. I support this and hope many others can experience the joys I have. Peace and luck Guardians!! 😎
