you can be the most deadly tier 1 operator to ever live, trained in every martial art known to man, and a ball of pure muscle and freakish dense bones with crazy reach

…and still be dropped by a semi-coordinated group of willowy, gangly attackers (with a plan of attack) that combined might only barely hit your weight class

I would contest that this is entirely dependent on what the state of weapons & armaments technology of the day is. It’s not as if Knightly Castes have never been an effective paradigm. But either way this dude was jumped by like 30 people, seemingly of both men & women. The personal qualities of whoever is being entrapped is not the most relevant factor in this situation.
