flawless raids are not that difficult with a good team. Flawless Trials is not even in the same book. Raids, you're going up against AI that is pre-programmed for one single thing. Trials has millions of variables and talents. If you're not the best, do what I did that helped me get my flawless seal, and play with people that not only elevate your game play, but also team shoot (you'll eventually get credit for the kills), and coordinate call outs. Strategy is key, especially on different maps, and based on how the other team plays.
