That is a good thing. After people witnessing Scorpion in Injustice they can see why having the back to block would be a bad thing. However both back to block, and a block button would be good too though.
lol I ain't complaining about it as I would use Scorpion in Injustice, but NRS felt that a block button was needed. Though MK's always had a block button.
lol what you mean? MK1-MK3 had a block button, and as far as 3D MK games goes MK4-MK9 had a block button too. Only Injustice has a back to block option in NRS games. Other than that it was always a block button to block with.
