I have played a season so far in dynasty. It is better then 11, (which is not much of an accomplishment) but unless you tweek sliders it is either way to easy or way to hard on default settings. There are still tons of money plays, blocking animations seem better, but they don't actually block people half the time, and just run up field letting the hole collapse on you... secondaries are shit, you almost just want to blitz every down.. if the QB has anytime at all they are going to rocket a shot to the receiver.
And why do they take gang tackles out? (or make it really hard to trigger?) It is always so stupid when the ball carrier and a tackle get warped up in some animation, and everyone around them is just diving and falling to the ground. lol
Like most sports games now, you can tweek the sliders to make it a lot better, but if you want to play ultimate team or online you have to deal with all the nonsense. :/
