All of the bolded is the problem with the gameplay: They're not needed and need to be updated. Tradition is just a binding mentality. There's no logical reason for a block button in a 2d fighter. The Scorpion's teleport excuse is lame because it used to be slower and easily crouched under. It used to be a primary anti-zoning tool and not a combo starter.
Not even Tekken, the game Boon is obsessed with has a block button. It's arbitrary to have to press two button just to block low and two different button commands to break throws. It works in Tekken because you can clearly see what type of throw is being used and characters fight from different angles (dodging). MK only has left and right to worry about. Logic, not just throwing things into the cauldron and calling it "different". They need to have logical application, which the above mechanics do not. The same can be said for how arbitrary it is to delay wake-up and counter from the ground.
Even the dial-a-combo system is conflicting with the purpose of neutral play, where it's more about memorization than reaction and reads. I know it's not going anywhere (facepalm), but can the game and it's characters not be all about who has the best strings? Please? Good gracious! Where are the ground/air 2-in-1 combos at? Where's interaction with specials vs specials and normal attacks vs specials? Special and normal attacks with unique attributes for neutral like how Jade's glow invalidates projectiles for a short time and back kicks that don't knockdown, but allow standing combos. There needs to be more of that type of nuance in strings, normals and specials. More branching points in strings with dash/special cancels, etc. It needs the back-n-forth play in every aspect and keeping players honest. That's neutral.
If the game is going to be based around neutral, a player should have the option of not relying on strings to succeed. Strings are not neutral play. They're the end result of winning neutral and predictable (memory-based) strings leads to a stagnated game.
There's really no purpose to Fatal Blows except to heavily hand-hold. Why not give each character unique traits at 30% or lower health? Something like the traits from Injustice. That would require actual skill instead of some auto-combo that does all the work for the player. Also, change breakaway into a MK 9 breaker. That way, players can break on the ground as well and not drop out with the chance to attack the aggressor right away. It goes right back to a full neutral position. And finally, lose the chip-kill. Make players earn the last hit. Those would be better (and more exciting) comeback mechanics.
