I get the idea of abilities is to help close the skill gap between players, and to make the game more "arcadey", but it's made the game less enjoyable for me. You can completely wipe out an opponents run game by putting Inside Stuff/No Outsiders on all of your lineman or a player can get hit 3 times on the same play and still be running forward. Also, it ruins the market value of players as evidenced by the new combine players, so if you want to be able to field a competitive team, you have to invest into every new promo.
And on a side note, a lot of the game mechanics are broken. Players reacting to a route by completely abandoning their zone, defenders backing off from a tackle once someone engages with the ball carrier, etc.
On top of this, it seems like EA doesn't really care about the people playing the game. Their reaction to the "95+" pack combined with the mess up with ranked rewards (still haven't gotten Brents) has really put me off from wanting to play.
