Judo is, along with Wushu, a highly luck-based mode (Yeah, mode. Not mod, as it's only game rule changes). Some might argue against this, but let me settle this.
Judo is, as Oracle said, about hitting first. If you hit first, you are likely to get the first dismembement. That means many relaxed frames for the opponent, whilst your force goes on. This gives you an ideal position to DQ your enemy next turn. I have never ever seen a stylish game of Judo. It seems like when I was a beginner. I pulled a move, waited for five-six turns, then changed one joint. It looks so horrible.
Wushu, now. That's a stylish mode. But most people make premade moves, simply because they don't dare to improvise and because it's effective. With its long turn frame and engage distance, it's the ideal mod to make moves and follow through in. For instance, who haven't seen the legs-spread-wide, arm down-behind-the-back-sweep? It is effective, which is why it is so much used.
These two modes are not very good spectator modes. Single Player is ONLY a spectator way of playing. I will also say, as an aikido enthusiast, that aikido is also very watcher-friendly as it can deliver both enduring, intense games and the really swift DQ. Both highly entertaining. TK is another mod that will entertain a viewer.
Still, your point is single player, and you're right. I want to be good at single player myself. For all you single players: I love what you're doing, but I hate you for doing it so well!
Toribash needs several variations of players. Single Player, as the most stylish players. Aikido/TK players, as the players who read the enemy's move the most, and Judo/Wushu players, who plan and plan to find the ultimate move.
