This trophy is glitched as heck. Even after meeting the requirements it might not pop your trophy. So to play it safe get each Class to Level 20. Hopefully it pops for you. If it doesn't, it will require a hard reset. Delete your profile/saved data and the game. And just play one full game as each class, leveling it up per say. Dice also patches their game in which, trophies get buggy. So playing on a fresh downloaded BFV is the safest way of achieving this. I will provide my own video guide if you rather have this spoken to you. I will say, after deleting the game the trophy can pop, but still might not. So playing a full game/match will be a great option in getting it to pop. You can check your progress/score by going under your profile. Find it at the main menu. Take care! -KC
