However we aren't talking about you, we are talking about people with little/no arena experience coming here and 

a) being overwhelemed by the characters, 
b) put off by the banter which can approach hostile, 
c) realize that the arena fighters expect more in a fight than a few lines or a paragraph.

I have done simple instructional fights where I show people how to attack and defend. I have used weapons or hand to hand. Each person is different but many realize that to fight a T1 fight is much harder than a casual fight where you can simply say "Biff shoots Rilla with his .50 DE  and then cuts off his head with his vorpal blade *snicker snack* and off with his head"

The issue is not the quality of instructors, rather the student's desire to learn to fight T1.  I think it is great you had your learning expereince, however it is unique to you. How to translate that to others if they do not stick around?
