I meant that a very powerful Epic has more abilities at his disposal in order to avoid it. Example: Steelheart avoided his because he was so powerful, he was able to take over a city, murder a whole lot of people, even employ people to write propaganda. All so there would be no one left so that didn't fear him. A weaker Epic wouldn't be able to go to such lengths.
Also, even if a High Epic did face his or her fear, and lost their weakness, it doesn't necessarily have any baring on the narrative. It's obvious very few if any Epics have faced it, as all the known ones are still murderous sociopaths, and the world is big enough that it's plausible the few that have they haven't bumped into. Furthermore, it's obvious in the end Epics will be taken down by some other means than facing them one by one and killing them, since there's supposed to be thousands of them.
So yeah, not that I believe my theory *is* the truth, just that I don't think the problem of High Epics with no weakness means that it isn't.
