I think it's best to start by looking at the history of pures (or what i think it is :D ). There was once a group of pkers who wanted more out of the wilderness, a way to have more fun and excitement. So they invented 1def pures. With the fact that they couldn't wear any good armor or defend themselves, they could have faster more rushing battles. When 2 pures fought each other they would both hit high, not have the ability to safe because they are constantly being damaged, and be able to k.o. easily. Thus the result would be a face paced battle that, to some people, is a lot of fun. But then one day somebody thought that a pure could be used to easily defeat a normal character with the thought that defense levels weren't really that effective. They also thought that since they could lower their combat level, thinking that def levels meant little, they could kill easier. The modern mislead pure is born and everything goes downhill from there. They seem to have forgotten that pures (from what i know) were once meant to fight other pures. In truth def pures with high range or magic could probably beat a 1 def pure any day.
