Asymmetric fighting is kind of a weird one for that.
Where you should fight with better tools on better ground than the other guy. Which makes sense. Fight with an advantage if you can.
But then people get really strange. Like in the video, he is like. If you sports fight me. I will eye gouge, nut shot, bite, whatever. And therefore it will become an asymmetric fight.
I'm a big fan of asymmetric training. But the proper way to do it (IMO) is to establish different goals/victory conditions/rules of engagement for the different participants.
For example, I've expressed the opinion before that Aikido/Aikijutsu* techniques primarily make sense in the context of a swordsman being able to avoid being surprise dogpiled by a group of unarmed attackers before he can draw his sword. I didn't come up with the theory, but it helps explain a lot of Aikido/Aikijutsu techniques and tactics. The swordsman doesn't want to engage in a clinch to establish control for a wrist lock, because that enables his attackers to drag him down and prevent him from drawing the weapon which will allow him to win the fight. Instead, he wants to evade and stay at longer distances. Wristlocks aren't the goal. They're just a tool to force someone to let go if they are desperately trying to hang on to you long enough for their friends to catch up and tackle you.
So - how do we pressure test this idea? You don't do it by having two people square up to spar. You assign roles. One person has a long weapon like a training sword in their belt. Start in a semi-confined space like a ring or cage, with two unarmed attackers who get to initiate the test from within 3-4 feet of the defender. Attackers win if they can get a clinch which prevents the defender from drawing his weapon or drag him to the ground or get him pinned against the ropes/cage wall. Defender wins if he can draw his weapon and have his weapon arm free so that he could start swinging. You can make all sorts of adjustments to the basic scenario - more or fewer attackers, more or less space to operate in, attackers starting from different distances. You could even ditch the weapon and make it a simple escape drill - defender has an exit that they need to make it to, attackers need to stop them from making it to the exit. I think this might also be a context where Aikido tactics might be helpful.
I actually corresponded a little bit with Rokas back before he fully transitioned over to MMA and suggested that he try this approach to pressure testing, but I don't think he ever took my advice.
*(I reference Aikijutsu, because Aikido doesn't date back to the era of sword bearing samurai, but it was derived from Daito Ryu Aikijutsu, which does claim such a history. Although the documented history and koryu status of Daito Ryu itself is somewhat questionable, it probably derives from some older koryu art(s)).
