If Elend was able to use Lerasium without being a misting, that should mean that people could use Atium (or any god metal for that matter) without even becoming a misting. So when Preservation (aka Fuzz) affected 1/16th of the population, was that just to give them a hint as to what he was doing or did he actually need to make them into mistings? (Unless Elend was actually a Lerasium misting which destroys the whole question)
