Okay so the concept of luring mobs towards traps is a strategy that people in this world are aware of? Then why was this ever a problem for the highly-ranked "Holy Sword"? Surely they were capable of coming up with this as well. Is there any reasonable answer besides "it's what needed to happen for the story to exist"?
It might be more effective in large raid groups like this, as opposed to a small group of individual fighters. In a raid like this, they've got a commander to coordinate and give orders, with just the party it might not be like that

most of it's already been said. I'll just say that, there still should have been a time at the beginning when they were all the same level. At a time initially where the mc can only really do damage by drawing aggro, their abilities probably let them do direct damage before the monster is even aware. On top of being safer, it would allow them to deal with more powerful and dangerous monsters and grow faster because of that. They would have to seriously restrain themselves to prevent an exponential gap from forming between them.
Like that the dude was actually reasonable and actually had a valid reason to not go with the MC's suggestion. Way to often do they make these types of characters way too do dumb just to forward the plot of to make the MC look better.
