In my opinion, the worst trophies of BF3 were the co-op missions. I could never figure out how to fly the damn helicopter, or get a good partner. I remember posting on PS3T for partners, and people would tell me they were good and then they'd be awful. I eventually just gave up.
If you need help with the helicopter and/or Bulleyes (sniper mission) trophies, let me know. I have a headset.
At least, in Battlefield 4, there is no "Get one of every ribbon" trophy. It was the most annoying and tedious trophy, pre-patch. There was no consistent way to get the suppression bonus. For the ribbon, you needed seven suppression bonuses in one game.
I had six of them by chance and luck a few times. Of course, the game ended in the next couple of seconds which made me very annoyed.
Post-patch, you get suppression bonuses for shooting in the general direction of someone. They also reduced it to four bonuses for the ribbon.
As for Battlefield 4, I might have to skip it. I feel like an idiot whenever I play the beta. I know how to play the game and be a good team mate. Unfortunately, the controls prevent me from being effective. On foot, it is a minor annoyance. For vehicles, I might as well have a giant target on whatever I am driving.
"Hey guys! Free kill!"
I can not drive, shoot, and even get out of the vehicle without looking like an idiot.
What would you think the backlash would be if Call of Duty changed their controls?
It it works, don't change it!
