And I wasn't trying to say: "The X-Men should only fight mutant-hunting Sentinels once, and then never have that problem rear its ugly head again, because a second Sentinels story would bore me to death." I was only saying there should be other themes mixed in for variety, year after year, to keep us guessing! Instead of just all that nonsense about "mutants should conquer the world!" and "we should exterminate mutants to make sure they don't conquer the world!" (Two sides of the same coin, basically.) One benefit would be to remind the readers that even if the X-Men weren't mutants (but had the same powers and personalities), they'd still be superheroes who could handle a wide range of emergencies as necessary!
The Ghostbusters were not "cops" or "superheroes" in the first place. They were specialists; a small group of businessmen who were somewhat competent at dealing with ghosts . . . and would have been utterly helpless and clueless if suddenly confronted by, let's say, a gang of ordinary bank robbers armed with automatic weapons. So I don't expect them to do more than just use their special gear to deal with the one type of problem they actually know how to deal with!
The main point with Buffy (the way I look at it) would be that she did not literally fight vampires and nothing but, every day of the week, even though her series title was "Buffy the Vampire Slayer!" She branched out more than that. You didn't know for a fact: "Last week had a vampire as the main villain, and so does this week's episode, and so will next week's episode, all the eway through to the end of the series!" Granted, the selection of adversaries for her was somewhat limited by the basic premise that Buffy lived in a world where virtually any kind of "super-powered" threat was going to be "supernatural" in some way, rather than just "alien" or "wearing a high-tech battlesuit" or "freakishly altered in a radioactive accident" or whatever.
That's in sharp contrast to the premises of the MU and the DCU, where there are a wide range of possible explanations for why a particular villain has exceptional abilities which allow him to present a real challenge to the superhero whom he is currently clashing with. If an individual superhero, or entire team of them, is going to operate in the MU or the DCU, I like to see the writer of any given title take full advantage of the many possibilities instead of insisting, for instance, that "only gangs of evil robots ever get to cross swords with the heroic Metal Men."
