After giving this free flow system deeper looking into, it kinda works for Batman, but it's terrible for Spider-Man, cause:
1. Spider-Man has superhuman strength, he should take down thugs easier
2. What is described to be a button masher is more stylistic and less of a painful button masher than this free flow, and each move actually does have different effect
3. Look at the last line in the point above, yeah, I tried it, but no matter how different the attacks in BAA, the same effect for each attacks, the same number of attacks to subdue each thug
4. How exactly did you believe in this free flow? It's a sore thumbing button masher, and some moves can only be used if instruction to use them is displayed
F*** that over glorified repeated button tapping with little analog dancing
