While I get that insults add more flavor, it really wasnt the case this time for the instructor vs student. I can see that even if they are from opposing sides, they did respect each others ability. Some quick remarks here and there, but what got me was I could feel the will to beat the other guy in the fight. Insults in that instance were unnecessary. It was battle of the skills, just the way I like it and just my personal opinion.
Sort of like the first meeting of the UN vs Anti UN Ace. It really was a great moment.
