If I wanted Street Fighter or Skull Girls, I will play Street Fighter or Skull Girls.
I can understand wanting to keep the other ones, but unique air normals? You really don't want that?
Anyway, despite using the engine, this is NOT MK, NRS should branch out a bit and try new things.
Its a T rated game so all the finishers would suck anyway, just like MK vs DC, no need to slow the game down with them.
I would like to see how MK9s engine would be with back to block, would be an interesting experiment to see if the block button really does hinder peoples opinion on the game.
Combo breakers make watching the game on the stream annoying for spectators, it slows the game down to much, and its not like Breakers were always a huge part of the series anyway, first 4 games didn't have them. Just have better balance, more hitstun degradation, and stricter damage scaling(with out being overbearing). Like it or not, but fighting games are now a spectator sport for a lot of people, and right now MK is a chore to watch for a good majority of them, due largely in part of breakers, that and the general wonkiness of the game.
Or at the very least make breakers more in line with anime game bursts, make them harder to get, and make them punishable.
I'm a crazy person though, so you don't have to take any of my opinions seriously.
