The recent patch and tuner update for Fight Night Champion was generally well received though some issues still remained. Another tuner set is expected to arrive next week and hopes to address at least one of them. Jab spamming, particularly exploited online, is what is being targeted in the next update.
EA Sports has also noted that another patch is in the works for the game and that it will include fixes for some of the crashes and freezes being experienced both online and offline. Considering that is still being developed it shouldn’t be expected to arrive for another month or so however.
