Isaac Frost and Bishop are in the game because of the community over-referencing Fight Night as better gameplay, when really it's kicks or kicking range in mma (and ground game) that make gameplays incomparable. to be fair, they then also added Stand and Bang mode for those players.

also reacted same way, especially in UT when Frost and Bishop were added into gameplay with higher tier available cards than most of roster. But adding them was more a tongue and cheek gesture saying you really can't take the gameplay too seriously considering look who's now in the gameplay. so it's a game and more about only trying to make the game(play) more "fun" and to not really take gameplay that seriously.
