Well I dont hate 3D flying. It is the best flying for me. Lately yea I have been going a little crazy flying. But AMA says that all flying fields should have a dead zone where planes dont fly. Example The barrier then a space then the runway. Keep the planes over the runway part.
I just know some people hate 3d because they cant do it themselves. Well they could solve that by practicing!! Took me 7 years. Anyway I would say just let people 3d where they wont just as long it is not too close the the flightline.
(See us 3Ders get mad at circle flyers) lol
