If you have reached a point where you are trying to claim that doing Batman's job should not involve having to deal with Batman's rogues so you can either state the thread premise is unfair, or talk about how people can "do Batman's job" as long as they don't have to deal with various of Batman's actual villains, then that is I think the most defining statement on these threads and the posts that tend to happen in them, and the reasons why people make them, in the entire history of these threads.What's Batman's job?
Do you really feel that "dealing with Batman's villain roster and the things they get up to" is not a part of Batman's job? If it is, and the people you want to say can handle it, do not have the capacity to handle that, then they can't do Batman's job.
That's really pretty simple.
So let's start with this. Why do you think all the people with wildly inferior detective abilities to Batman can handle Batman's rogues gallery with a similar level of effectiveness? Or the people who are simply nowhere as intelligent as the guy, period.
I've made my case for Nick Fury for example. He's amongst the greatest spies in comics, and capable besides of creating and running whole advanced spy networks, sometimes basically out of his ass, in relatively short periods of time. Those two qualities will let him compensate for a lot of crap he otherwise lacks in tracking and uncovering crap.
