I don’t inherently dislike them, but I do find them lackluster when you think about it and see that there’s hardly any dialogue to reflect the changes of becoming a Grail Knight on Kruber. When you compare the implementation of Grail Knight with Outcast Engineer it becomes quite apparent. Especially because Grail Knight being such a drastic change would require far more work than just some lines saying peasant and some others more suited to a bretonnian character (Praising/Thanking/Pleading for protection from the Lady instead of Taal/Sigmar).
My main gripe with those lines is that they’re the most present voice lines as a Grail Knight Kruber and it makes our boy de Mandelot embody the Virtue of Noble Disdain to such an extent that it feels out of character for him. Of all Knightly Virtues, and despite being a heritage Mandelot and Parravon, I feel Kruber would embody Empathy the most of all virtues. His dialogue hardly reflects that.
I feel like Kruber’s dialogue as a Grail Knight isn’t finished tbh, someone mentioned the Covid-19 outbreak impacting the recording of said voicelines and I believe that to be the case. There are certain lines of dialogue where whatever he says does not match the subtitles and I believe that’s a reflection of this situation. For instance, Kruber calls the team goodfellows instead of mates, and I’m pretty sure goodfellows is a known bretonnian way to address their friends (I can’t remember especifically where, but I believe it’s in the Knights of the Grail 2ed RPG Book). There are some lines where he still praises Sigmar or Taal but the subtitle is quite different, where he says something relating to his status as a Grail Knight or where he praises the Lady. For instance, when you get the killing blow on Bodvarr Memespreader, Kruber might praise Taal or Sigmar for the death of the Champion but the subtitles he says something along the lines of “The champion is dead, an expected ending for believing he could contend with a Grail Knight.”
TL;DR I don’t hate the lines, but I feel they’re a poor representation of Kruber as a Grail Knight and more dialogue and voicelines are needed.
