Do you think henchmen/mooks who recognize the WoL but attack anyway are silly?

The issue is more that they have no place or relevance in the narrative. With Bismarck for example, the story is directly set up for WoL to be alone so that you can be ambushed and the key to Azys Lla stolen. In order to think that there were other people there, you'd also need to think that they all immediately left literal moments after killing Bismarck, before you even got the key. Yes, real people aren't constrained by your progress in the story, but it's beyond reasonable belief that something like that would happen within the world itself.

- "Sure, meet you at the Forgotten Knight." /teleports away.

I'd hardly say it's beyond reasonable belief for that to happen within the world itself. Even makes sense within the world really, the primal had been slain and they were all probably soaking wet from fighting a flying whale. I'd want to go and get changed ASAP too.
