pointing out exceptions does not change what i said. the majority of comedy slice of life mangas don't last past chapter 500 if they even get there. cope and seethe.
The majority of manga in general don't make it past chapter 200, your logic is just horribly flawed. Also these aren't exceptions these are the reality because there are MANY more examples to this iceberg that proves that you have no idea what you're talking about. The genre a series is from has very little to do with the longevity of the series in the realm of manga, all that matters is whether or not the mangaka can think of enough material to keep the series going and/or if the audience is willing to stick with the series that long, the fact is that Iruma-kun has shown very few signs of slowing down, past that you're just making assumptions based on your biases. Sorry mate, but you're just flat out wrong, nice try though, have a good day.
Edit: Oh, and before you try to come back make further bogus claims, make sure you have some evidence to back it all up, statistics, examples, whatever, because right now, the burden of proof is all on you.
