I prefer PvE above all else, in every game ever. I buy games for the stories, and for the chances to co-op missions with other players. I hated all of the CoD games for their major lack of story and focus on PvP. The only things I liked in those games were Spec Ops missions. I finally started playing Crucible because my fireteam friends were tired of Raids and Strikes, as was I. It started out rough but I've gotten better. Honestly if you jump into 6v6 with at fireteam of at least 4 friends, you'll usually do just fine. Playing alone with people you don't know destroys the fun and makes the game infinitely harder. I still prefer PvE but I've learned that Crucible can be fun with the right team.
