Because see, people were jumping exceptionally well, eons before Hunters was even created - in form FAR FROM what we see in the Hunter Ring today.
Lets go back to the creation of Hunters - which is only found in North America *so what, all those riders in GB and other countries who don't ride Hunters...aren't jumping safe?* derived from Fox Hunting. Majority of Eventers, were Fox Hunters and from the Millitary.
Im not saying if you don't do hunters you suck at riding. Im saying its stupid to say we don't have time to look like 'hunters.' like 'hunters' a dirty word... good hunter position is one in the same as good hunting, eventing, military position, good 'hunter' position is good jumping position.
