Those speedruns are frankly unprofessional.

Well, half the challenge (in my opinion) is the delays between the opponent's attacks. You have to be "on edge" while they're idle, so you can react to them. This is a two-fold reaction:

1. Reacting to when they start attacking
2. Reacting to specifically which attack they are doing

Both of these reactions make speedrunning this game fun.

Madness mode removes the first reaction, making the game significantly easier. I don't really understand why you think madness mode is preferred, but maybe in your circle of this community.
