Multiplayer trophies in any single player game are the worst especially those that rely on luck or even worse world ranking like killzone 2 had trophies tied to being in the top 5, 3, and 1% of online players thats insane, the assassin's creed brotherhood multiplayer trophies rely on a lot of luck and I'm just not going to put in the time to hit max level it doesn't help that I just tried the multiplayer again and am so outclassed its sad. I'm usually willing to put in the work to 100% a game I like but multiplayer trophies kill that. I'm the guy who got big boss rank in mgs4 that requires you to beat the game without dieing being spotted or killing anyone and in under 5 hours for a game that usually takes 15 hours easy and there aren't even trophies for it so to me its more about beating the challenges set by the trophy requirements than getting the actual trophy though my ocd side likes to see the 100% complete.
